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

Using the graph, find the value of (i) p, when q = 4 and (ii) q, when p = 20.

Consider the following input/output table. Draw a line graph for it.

Now, use the graph drawn to predict the outputs for the inputs of 3 and 8, respectively.
