Answer
A
Kendra should have added 75 to the x-values to get the y-values.
B
Kendra should have added 7.5 to the x-values to get the y-values.
C
Kendra should have multiplied the x-values by 75 to get the y-values.
D
Kendra should have multiplied the x-values by 25 to get the y-values.

Explanation

Compare the first pair: when x = 1, y = 75, so the multiplier is 75, not 7.5. The other pairs confirm the same rule: 2 × 75 = 150 and 5 × 75 = 375. Kendra should have multiplied the x-values by 75 to get the y-values.
