Q2 of 26 Page 97

Write the equation of the line parallel to the Y-axis at a distance of 7 units from it to its left.

The equation of line parallel to Y-axis is x = a

a = -7 (because 7 units from left)


x = -7 is required equation.



X-Values


Steps to draw:


• On a graph paper draw the X-axis and the Y-axis.


• Since it is given that x = -7, draw a line on the left of the Y-axis at a distance of 7 units from it and parallel to it.
