(i) x + y = 3                         ...(1)

⇒ y = 3 – x

Table of solutions

We plot the points (0, 3) and (3, 0) on a graph paper and join the same by a ruler to get the line, which is the graph of the equation x + y = 3.

(ii)  3x - 2y = 4                        ....(2)

        2y = 3x - 4

Table of solutions

We plot the points (2, 1) and (4, 4) on the same graph paper on the same axes and join the same by a ruler to get the line which is the graph of the equation 3x – 2y = 4.

The region formed by the graphs of the given linear equations and y-axis has been shaded.
