3. This graph shows the linear relationship between commission $ earned (c) by salesperson and the number of sales he makes (s). Find the
constant of proportionality (r). Using the value for r, enter an equation in
the form of c=rs that represents the relationship between the
commission earned (c) and the number of sales (s).

c=8s (also sorry in advance if this is wrong )

Step-by-step explanation

40=r5

Divide both sides by 5 in order to find r

40 divided by 5=8

5 divided by 5 = 1

r=8

And the final answer is:

c=8s
