What is abscissa? . what do u mean by linear equation in two variable ?

Question

Answer

Abscissa is the point in system of coordinats which lie on x axis as in point (2,3) 2 is Abscissa........................ And......................Linear equation in two variable is a type of system which have two variables such as x,y and it gives the value of both at same time and when we put the value of x,y in equation in satisfies the equation.That's all

Answer

While plotting a graph we have two axis x& y and two points in form of( x,y) to plot on it , here the x is also called abscissa.   linear equation in two variables means that a equation which can be written in the form ax+by+c=0. & it can be also plotted in graph . the graph of these equation forms a straight line .on graph.

Answer

X coordinate is also known as abscissa...a linear equation which has 2 variables is callled linear equations in 2 variables..eg 2x+3y

Answer

Value of x is known as abscissa.Example (2,3) in this value abscissa is 2

Answer

Abscissa:
The abscissa is a term used in coordinate geometry to refer to the x-coordinate of a point on a graph. It is the horizontal distance of a point from the origin (0,0) along the x-axis. In simple terms, the abscissa represents the position of a point on the x-axis.

Linear Equation in Two Variables:
A linear equation in two variables is an equation that can be written in the form of Ax + By = C, where A, B, and C are constants and x and y are variables. It represents a straight line when graphed on a coordinate plane.

Explanation:
A linear equation in two variables represents a relationship between two unknown quantities. The variables x and y represent the coordinates of a point on a graph, and the equation describes the relationship between their values. The coefficients A and B determine the slope of the line, while the constant C determines the y-intercept.

Graphing a Linear Equation:
To graph a linear equation, we can use the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept. The slope represents the change in y divided by the change in x, and the y-intercept represents the y-coordinate where the line intersects the y-axis.

Key Points:
- The slope of a line determines its steepness. A positive slope means the line goes up from left to right, while a negative slope means the line goes down.
- The y-intercept is the point where the line crosses the y-axis. It has the coordinates (0, b).
- If the equation is not in slope-intercept form, it can be rearranged to find the slope and y-intercept.
- Every point on the graph of a linear equation satisfies the equation. By substituting the x and y values of a point into the equation, we can verify if it lies on the line.

Example:
Let's consider the equation 2x + 3y = 6. To graph this equation, we can find the slope-intercept form by rearranging it as follows: 3y = -2x + 6, y = (-2/3)x + 2. Now we have the slope (-2/3) and the y-intercept (2). By plotting the y-intercept and using the slope to find additional points, we can draw a straight line that represents the solution to the equation.

In conclusion, a linear equation in two variables represents a relationship between two unknowns, x and y, and can be graphed as a straight line. The abscissa refers to the x-coordinate of a point on the graph, representing its horizontal position. By understanding these concepts, one can solve problems involving coordinate geometry and analyze relationships between variables.
