Question

Draw the graph of the equation y – x = 2

Answer 1

We have,

y – x = 2

⇒ y = x + 2

When x = 1, y = 1 + 2 = 3

When x = 3, y = 3 + 2 = 5

Thus, we have the following table exhibiting the abscissa and ordinates of points on the line represented by the given equation. Plotting the points (1, 3) and (3, 5) on the graph paper and drawing a line joining them, we obtain the graph of the line represented by the given equation as shown in Fig.
