Question

Gina is investigating the two proportional relationships shown below. She claims that the proportional relationships have the same unit rate. Complete the table to represent the case where Gina's claim is correct.
y=5/2x
x = 0,4,15
y=0,?,?

Answer 1

Filling in the offered values for x, we have

... y = (5/2)·4 = 10

... y = (5/2)·15 = 75/2

The table values are y = 0, 10, 75/2
