DIRECTION : In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
Assertion: A point whose abscissa is 2 and ordinate is -3 lies in fourth quadrant
Reason: Points of the type (–, +) lie in the second quadrant.
  • a)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
  • b)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
  • c)
    Assertion (A) is true but reason (R) is false.
  • d)
    Assertion (A) is false but reason (R) is true.
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
DIRECTION : In the following questions, a statement of assertion (A) ...
We know that Points of the type (–, +) lie in the second quadrant. So, Reason is correct.
Also, we know that Points of the type (+, –) lie in the fourth quadrant. Hence, point whose abscissa is 2 and ordinate is -3 lies in fourth quadrant So, Assertion is also correct but Reason is the not the correct explanation of Assertion.
Correct option is (b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).

DIRECTION : In the following questions, a statement of assertion (A) ...
Assertion: A point whose abscissa is 2 and ordinate is -3 lies in the fourth quadrant.
Reason: Points of the type (–, ) lie in the second quadrant.

The given assertion states that a point with an abscissa of 2 and an ordinate of -3 lies in the fourth quadrant.

Explanation:
To understand this assertion, we need to recall the definition and characteristics of the quadrants in a Cartesian coordinate system.

Cartesian Coordinate System:
The Cartesian coordinate system is a system that represents points in a plane using two perpendicular lines, called the x-axis and the y-axis. The point where the x-axis and the y-axis intersect is called the origin (0, 0).

Quadrants:
The plane is divided into four quadrants, numbered from I to IV, in a counterclockwise direction. Each quadrant has its own characteristics based on the signs of the coordinates:

- Quadrant I: The x-coordinate (abscissa) is positive, and the y-coordinate (ordinate) is positive.
- Quadrant II: The x-coordinate (abscissa) is negative, and the y-coordinate (ordinate) is positive.
- Quadrant III: The x-coordinate (abscissa) is negative, and the y-coordinate (ordinate) is negative.
- Quadrant IV: The x-coordinate (abscissa) is positive, and the y-coordinate (ordinate) is negative.

Analysis:
Let's analyze the given point with an abscissa of 2 and an ordinate of -3.

- The abscissa is 2, which is positive.
- The ordinate is -3, which is negative.

Based on the characteristics of the quadrants mentioned earlier, we can conclude that the given point lies in the fourth quadrant because the abscissa is positive and the ordinate is negative.

Conclusion:
Both the assertion and the reason are true, but the reason is not the correct explanation of the assertion. The reason states that points of the type (-, ) lie in the second quadrant, which is incorrect. The correct statement would be that points of the type (-, -) lie in the third quadrant. Therefore, option B is the correct answer.
