Question

Draw the graph of each of the following linear equations in two variables:

y = 3x

Answer 1

y = 3x

It can be observed that x = −1, y = −3 and x = 1, y = 3 are solutions of the above equation. Therefore, the solution table is as follows.

x	-1	1
y	-3	3

The graph of the above equation is constructed as follows.
