Question

Drawing straight parallel lines to axes :
Draw the graph of x = 3.

Answer 1

The equation x = 3 means:Whatever may be y-coordinate, x-coordinate is always 3. Thus, we have

x	3	3
y	3	-4

Plot the points A (3, 3) and B (3 , -4). Join these points and extend this line on both sides to obtain the graph of x = 3.
