Plotting points

In order to plot an ordered pair we must have into account that the horizontal line corresponds to the first number in the parenthesis and the vertical line correspond to the second.

First, we are going to draw the first values of the ordered pairs on the horizontal line. Those are: 5, 10 and 25.

Each company has an ordered pair whose first number is five.

For company A, 5 is related with 15

For company B, 5 is related with 20.

So we rise 15 and 20 unities though the line of five to locate the first ordered pair for both

We do the same across the line of 10

Company A: 10 is related with 30

Company B: 10 is related with 35

We do the same for the third ordered pair of each company:

All the blue points correspond to company A and green points to company B, we draw a line across them

If we observe blue points every five unities we go to the right it grows 15 unities. The same happens with green points.

Since both grow always with the same speed (15 unities every five unities we go to the right) then

Answer: they both are proportional
