Study the table given below and draw a line graph for it.

Side of the square (in $\mathrm{cm}$)	$2$	$3$	$4$	$5$	$6$
Area (in ${\mathrm{cm}}^2$)	$4$	$9$	$16$	$25$	$36$

Is the graph drawn, a linear graph?

Plot a line graph for the variables $p$ and $q$, where $p$ is four times $q$. The equation is $p=4q$.

Using the graph, find the value of $p$, when $q=6$.

A bank gives $10\%$ Simple Interest on deposits by senior citizens. Draw a line graph to illustrate the relation between the sum deposited and the Simple Interest earned. Find from the graph, the annual interest obtainable for an investment of $₹250$.
