For this shape there are four points. The plotted ordered pairs are: M = (3, 9) N = (6, 0) O = (3, 6) P = (-3, 0)
All you have to do is multiply the BOTH x- and y-values by 1/3 on EACH ordered pair. And if it’s easier, you can divide by 3 as well. It’s the same thing.
M = (3, 9) = (3*1/3, 9*1/3) = (1, 3) N = (6, 0) = (6*1/3, 0*1/3) = (2, 0) O = (3, 6) = (3*1/3, 6*1/3) = (1, 2) P = (-3, 0) = (-3*1/3, 0*1/3) = (-1, 0)
(1, 3) , (2, 0) , (1, 2) , and (-1, 0) are your points.
Since we are finding the unit rate of the cost per comic, we will need to divide $5 by 20 comics which you will get 0.25 cents and divide $7.50 by 30 comics which you will also get 0.25 cents.Therefore, the unit rate and constant of proportionality is 0.25 cents.
