Question

write a linear equation in two variables X and y which represents a straight line parallel to y-axis in the Cartesian plane​

Answer 1

Answer:

Consider the equation y=2y=2, or y−2=0y−2=0. This is an equation with a single variable y. However, we can think of it as a two-variable linear equation in which the coefficient of x is 0:

(0)x+(1)y+(−2)=0(0)x+(1)y+(−2)=0

No matter what value we substitute for x, the value of y will always come out to be 0. Thus, all solutions of this two-variable linear equation are of the form (k,2)(k,2), where k is some real number.

What will the graph of this linear equation look like? Well, we plot all points in the plane for which the y-coordinate is 2:
