Rati Joshi answered |
Explanation:
The point (0, b) is a point in the coordinate plane, where the first coordinate (x-coordinate) is 0, and the second coordinate (y-coordinate) is b.
To determine on which axis or quadrant this point lies, we need to examine the values of the coordinates:
- The x-coordinate is 0, which means the point lies on the y-axis.
- The y-coordinate is b, which means the point is at a distance of b units from the origin, in the positive y-direction (since b is positive).
Therefore, the point (0, b) lies on the y-axis.
Option D, which says "y-axis", is the correct answer.
The point (0, b) is a point in the coordinate plane, where the first coordinate (x-coordinate) is 0, and the second coordinate (y-coordinate) is b.
To determine on which axis or quadrant this point lies, we need to examine the values of the coordinates:
- The x-coordinate is 0, which means the point lies on the y-axis.
- The y-coordinate is b, which means the point is at a distance of b units from the origin, in the positive y-direction (since b is positive).
Therefore, the point (0, b) lies on the y-axis.
Option D, which says "y-axis", is the correct answer.

Zachary Foster answered |
The correct answer is B: (y, x).
- The abscissa of a point is the x-coordinate.
- The ordinate of a point is the y-coordinate.
- Therefore, if the abscissa of a point is y and the ordinate is x, the coordinates of the point will be (y, x).
- The abscissa of a point is the x-coordinate.
- The ordinate of a point is the y-coordinate.
- Therefore, if the abscissa of a point is y and the ordinate is x, the coordinates of the point will be (y, x).

Explanation:
The Y-axis is the vertical line on a Cartesian plane. It is perpendicular to the X-axis, which is the horizontal line on the same plane. Any point on the Y-axis has an x-coordinate of zero because it lies directly on the Y-axis, which is a line passing through the origin of the plane. Here are some more details:
• Definition of abscissa: The abscissa is the x-coordinate of a point on a Cartesian plane. It is measured from the vertical Y-axis to the point in question.
• Understanding the Y-axis: The Y-axis is a vertical line that runs through the origin of the plane. It consists of all points with an x-coordinate of zero.
• Relationship between the X and Y axes: The X and Y axes intersect at the origin of the plane, which has coordinates (0,0). Any point on the X-axis has a y-coordinate of zero, and any point on the Y-axis has an x-coordinate of zero.
• Importance of the origin: The origin of the plane is the starting point for measuring coordinates. It is where the X and Y axes intersect, and it has coordinates (0,0). All other points on the plane can be located relative to the origin.
• Conclusion: The abscissa or x-coordinate of any point on the Y-axis is zero because the Y-axis consists of all points with an x-coordinate of zero.

Isha Nair answered |
Explanation:
Quadrants are the four regions in a coordinate plane which are separated by the x-axis and y-axis. These quadrants are numbered from 1 to 4 in a counterclockwise direction. Let's understand how to identify the quadrant in which a point lies:
- Quadrant 1 (Q1): This quadrant is on the right side of the y-axis and above the x-axis. The values of x and y are both positive in this quadrant. So, any point lying in this quadrant has positive values for both x and y coordinates.
- Quadrant 2 (Q2): This quadrant is on the left side of the y-axis and above the x-axis. The value of x is negative and the value of y is positive in this quadrant. So, any point lying in this quadrant has negative x-coordinate and positive y-coordinate.
- Quadrant 3 (Q3): This quadrant is on the left side of the y-axis and below the x-axis. The values of both x and y are negative in this quadrant. So, any point lying in this quadrant has negative values for both x and y coordinates.
- Quadrant 4 (Q4): This quadrant is on the right side of the y-axis and below the x-axis. The value of x is positive and the value of y is negative in this quadrant. So, any point lying in this quadrant has positive x-coordinate and negative y-coordinate.
Now, let's identify in which quadrant the point (3, 2) lies:
- The x-coordinate of the point is 3 which is positive.
- The y-coordinate of the point is 2 which is also positive.
Since both the x and y-coordinates of the point are positive, it lies in the Quadrant 1 (Q1).
Therefore, the correct answer is option 'A' which says that the point (3, 2) belongs to quadrant Q1.

Jyoti Kapoor answered |
The given three points are A(1,2) B(3,-4) and C(5,-6).
Let P (x, y) be the point equidistant from these three points.
So, PA = PB = PC
⇒ x^2 + 1– 2x + y^2 + 4 – 4y = x^2 + 9 -6x + y^2 + 16 + 8y = x 2 + 25– 10x + y^2 + 36 + 12y
⇒ – 2x– 4y + 5 = -6x + 8y +25= – 10x + 12y+61
– 2x– 4y + 5 = -6x + 8y +25
⇒ – 2x– 4y + 5 +6x - 8y -25=0
⇒ 4x– 12y -20=0
⇒ x– 3y - 5 =0....(i)
- 2x– 4y + 5 = – 10x + 12y+61
⇒- 2x– 4y + 5 +10x - 12y-61=0
⇒8x– 16y -56=0
⇒x– 2y -7=0....(ii)
Solving (i) and (ii)
x = 11, y = 2
Thus, the required point is (11, 2)

Zachary Foster answered |
The abscissa refers to the x-coordinate of a point. If a point lies on the x-axis, its y-coordinate (ordinate) will be zero.
Given that the abscissa is -3 and the point lies on the x-axis, the coordinates of the point will be:
(-3, 0).
Thus, the point is (-3, 0).

Sakshi Banerjee answered |
Finding the point on y-axis at a distance of 6 units in the positive direction of y-axis
Steps:
1. The point on y-axis is denoted as (0, y), where y is the y-coordinate of the point.
2. Since we want the point to be in the positive direction of y-axis, y should be positive.
3. The distance of the point from the origin is given as 6 units. Using the distance formula, we have:
- distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
- Here, x1 = 0, y1 = 0 (origin), x2 = 0 (point lies on y-axis), y2 = y
- distance = sqrt((0 - 0)^2 + (y - 0)^2) = sqrt(y^2) = y
- Therefore, y = 6
4. So, the point on y-axis at a distance of 6 units in the positive direction of y-axis is (0, 6).
Answer:
The correct answer is option C) (0, 6).
Steps:
1. The point on y-axis is denoted as (0, y), where y is the y-coordinate of the point.
2. Since we want the point to be in the positive direction of y-axis, y should be positive.
3. The distance of the point from the origin is given as 6 units. Using the distance formula, we have:
- distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)
- Here, x1 = 0, y1 = 0 (origin), x2 = 0 (point lies on y-axis), y2 = y
- distance = sqrt((0 - 0)^2 + (y - 0)^2) = sqrt(y^2) = y
- Therefore, y = 6
4. So, the point on y-axis at a distance of 6 units in the positive direction of y-axis is (0, 6).
Answer:
The correct answer is option C) (0, 6).

Saikat Verma answered |
**Explanation:**
To determine the quadrant in which a coordinate point lies, we need to consider the signs of its x and y coordinates.
Let's analyze the given coordinates:
- Coordinate (-2, 3): The x-coordinate is -2 (negative) and the y-coordinate is 3 (positive).
- Coordinate (3, -2): The x-coordinate is 3 (positive) and the y-coordinate is -2 (negative).
Based on these coordinates, we can determine the quadrants as follows:
- Coordinate (-2, 3): Since the x-coordinate is negative and the y-coordinate is positive, this point lies in the **II quadrant**.
- Coordinate (3, -2): Since the x-coordinate is positive and the y-coordinate is negative, this point lies in the **IV quadrant**.
Therefore, the correct statement is option **D: Coordinate (-2, 3) lies in II quadrant whereas (3, -2) lies in IV quadrant**.

Jaideep Sharma answered |
**Explanation:**
The equation of the x-axis represents all the points that lie on the x-axis. The x-axis is a horizontal line that intersects the y-axis at the origin (0,0).
The equation of the x-axis can be written in the form y = k, where k is a constant. Since the x-axis is a horizontal line, the value of y remains constant for all values of x.
To find the equation of the x-axis, we need to determine the value of y that remains constant. At every point on the x-axis, the value of y is always 0. Therefore, the equation of the x-axis is y = 0.
**Option C: y = 0**
The equation of the x-axis represents all the points that lie on the x-axis. The x-axis is a horizontal line that intersects the y-axis at the origin (0,0).
The equation of the x-axis can be written in the form y = k, where k is a constant. Since the x-axis is a horizontal line, the value of y remains constant for all values of x.
To find the equation of the x-axis, we need to determine the value of y that remains constant. At every point on the x-axis, the value of y is always 0. Therefore, the equation of the x-axis is y = 0.
**Option C: y = 0**

The point D(3, -6) lies in the IV Quadrant. Explanation: In the Cartesian plane, the X-axis and Y-axis divide the plane into four quadrants. The I Quadrant is where both x and y are positive. The II Quadrant is where x is negative and y is positive. The III Quadrant is where both x and y are negative. The IV Quadrant is where x is positive and y is negative. The point D(3, -6) has a positive x-coordinate and a negative y-coordinate. Therefore, it lies in the IV Quadrant.

Samaira Kapoor answered |
Explanation:
- The point where X and Y axes intersect is known as the origin.
- It is denoted by the letter 'O'.
- The coordinates of the origin are (0,0).
- The X-axis is the horizontal line that runs from left to right.
- The Y-axis is the vertical line that runs from top to bottom.
- Together, they form a rectangular coordinate system, also known as a Cartesian coordinate system.
- The coordinates of a point in this system are given by an ordered pair (x, y) where x represents the distance from the origin along the X-axis and y represents the distance from the origin along the Y-axis.
- The origin is an important point in mathematics and is used as a reference point for many calculations and geometric constructions.

To understand this, let's break down the information given:
- x-axis: The x-axis is the horizontal line in the coordinate plane. Any point on the x-axis will have a y-coordinate of 0 because it does not move up or down from the axis.
- Distance of 4 units in the negative direction of x-axis:
- The x-axis has a positive direction (towards the right) and a negative direction (towards the left).
- Moving 4 units in the negative direction means moving 4 units to the left from the origin (0,0).
- Coordinates:
- When you move 4 units to the left on the x-axis, the x-coordinate becomes -4, and since the point is on the x-axis, the y-coordinate remains 0.
Therefore, the point that lies on the x-axis 4 units in the negative direction is (−4,0)(-4, 0)(−4,0).
This corresponds to option (b) (-4, 0).

**Explanation:**
The point (0, 9) lies on the positive direction of the y-axis. Let's break down the options and analyze them one by one to understand why the correct answer is option 'B'.
a) In quadrant IV:
Quadrant IV is the bottom right quadrant on the coordinate plane. In this quadrant, both the x and y coordinates are positive. However, since the x-coordinate of the given point is 0, it does not lie in quadrant IV.
b) On the positive direction of y-axis:
The positive direction of the y-axis is the upward direction. Since the y-coordinate of the given point is 9, which is positive, it lies on the positive direction of the y-axis. Therefore, option 'B' is correct.
c) In quadrant III:
Quadrant III is the bottom left quadrant on the coordinate plane. In this quadrant, the x-coordinate is negative, but the y-coordinate is positive. Since the x-coordinate of the given point is 0, it does not lie in quadrant III.
d) On the positive direction of x-axis:
The positive direction of the x-axis is the rightward direction. However, since the x-coordinate of the given point is 0, it does not lie on the positive direction of the x-axis.
Therefore, the correct answer is option 'B' because the point (0, 9) lies on the positive direction of the y-axis.

Explanation:
Quadrants in the Coordinate Plane:
In the coordinate plane, there are four quadrants labeled as I, II, III, and IV. The quadrants are separated by the x-axis and y-axis. The signs of the x and y coordinates determine in which quadrant a point lies.
Coordinates of the Point:
The point C(-5, -2) has x-coordinate as -5 and y-coordinate as -2.
Identification of Quadrant:
To determine in which quadrant the point C(-5, -2) lies, we need to consider the signs of the x and y coordinates.
- Since the x-coordinate is negative (-5), it means the point lies to the left of the y-axis.
- Since the y-coordinate is negative (-2), it means the point lies below the x-axis.
Location of Point C:
Based on the signs of the coordinates:
- The point C(-5, -2) lies to the left of the y-axis (negative x-coordinate).
- The point C(-5, -2) lies below the x-axis (negative y-coordinate).
Conclusion:
Therefore, the point C(-5, -2) lies in the III Quadrant of the coordinate plane.

EduRev Class 9 answered |
The abscissa of a point refers to its x-coordinate in the Cartesian coordinate system.
- On the x-axis, the y-coordinate (ordinate) is always 0, while the x-coordinate (abscissa) can be any real number.
- This means that any point on the x-axis is of the form (x, 0), where x can be any number.
Thus, the correct answer is:
c) any number.

Understanding Distance from the Y-Axis
To determine the distance of a point from the y-axis, we need to focus on the x-coordinate of the point.
Point Coordinates
- The given point is (3, 2).
- In this point, '3' is the x-coordinate and '2' is the y-coordinate.
Distance from the Y-Axis
- The y-axis is represented by the line where x = 0.
- The distance from any point (x, y) to the y-axis is simply the absolute value of the x-coordinate.
Calculation
- For the point (3, 2), the x-coordinate is 3.
- Therefore, the distance from the y-axis is |3|, which equals 3 units.
Conclusion
- The distance of the point (3, 2) from the y-axis is 3 units.
- Hence, the correct answer is option 'A' (3 units).
This understanding helps in visualizing how points relate to the axes in a Cartesian coordinate system.

Sayali Shah answered |
**Explanation:**
To understand why the correct answer is option 'B', let's first review the four quadrants on the coordinate plane:
1. **Quadrant I:** It is located in the upper right portion of the coordinate plane where both the x-coordinate (horizontal) and y-coordinate (vertical) are positive.
2. **Quadrant II:** It is located in the upper left portion of the coordinate plane where the x-coordinate is negative and the y-coordinate is positive.
3. **Quadrant III:** It is located in the lower left portion of the coordinate plane where both the x-coordinate and y-coordinate are negative.
4. **Quadrant IV:** It is located in the lower right portion of the coordinate plane where the x-coordinate is positive and the y-coordinate is negative.
Now, let's consider a point with both coordinates positive. This means that the x-coordinate is positive (greater than 0) and the y-coordinate is also positive (greater than 0).
Since the x-coordinate is positive, the point cannot lie in Quadrants II or III, as these quadrants have negative x-coordinates. Therefore, the point must lie in either Quadrant I or Quadrant IV.
However, since the y-coordinate is also positive, the point cannot lie in Quadrant IV, as this quadrant has a negative y-coordinate. Therefore, the only quadrant where a point with both positive coordinates can lie is Quadrant I.
Hence, the correct answer is option 'B' - the point lies in Quadrant I only.

4. **Quadrant IV:** It is located in the lower right portion of the coordinate plane where the x-coordinate is positive and the y-coordinate is negative.
Now, let's consider a point with both coordinates positive. This means that the x-coordinate is positive (greater than 0) and the y-coordinate is also positive (greater than 0).
Since the x-coordinate is positive, the point cannot lie in Quadrants II or III, as these quadrants have negative x-coordinates. Therefore, the point must lie in either Quadrant I or Quadrant IV.
However, since the y-coordinate is also positive, the point cannot lie in Quadrant IV, as this quadrant has a negative y-coordinate. Therefore, the only quadrant where a point with both positive coordinates can lie is Quadrant I.
Hence, the correct answer is option 'B' - the point lies in Quadrant I only.
