Question

Drawing straight parallel lines to axes :
Draw the graph of y = 5.

Answer 1

The equation y = -5 means: Whatever may be the x-coordinate, the y-coordinate is always -5.

x	-2	6
y	-5	-5

Plot the points A (-2, -5) and B (6 , -5). Join these points A and B and extend this line on both sides to obtain the graph of y = -5.
