# Draw a graph for the following.

(i) Is it a linear graph?

(ii) Is it a linear graph?

**Solution:**

Reasoning:

A line graph which is a whole unbroken line is called a linear graph.

Steps:

(i) Choosing a suitable scale,

For x-axis, 2 unit = 1 cm and for y-axis, 2 unit = 5 cm

We can represent the side of a square on the x-axis and the perimeter of that square on the y-axis. A graph of the given data is drawn as follows.

It is a linear graph.

(ii) Choosing a suitable scale,

For x-axis, 2unit = 1 cm and for y-axis, 2 unit = 5 cm

We can represent the side of a square on the x-axis and the area of that square on the y-axis. A graph of the given data is as follows.

It is not a linear graph.
