Question

Drawing straight parallel lines to axes :
Draw the graph of x = 0.

Answer 1

The equation x = 0 means; Whatever may be the y-coordinate, x-coordinate is always 0.

x	0	0
y	3	-3

Plot the points A (0 , 3) and B (0, 3).
Join the points A and B and extend this line to obtain the graph of x = 0.
