Which equations have a unit rate of change of 4.5? select 2 answers

A. y = 62 + 4.5x

B. c = 4.5 + 3 (h - 1)

C. c = 12 + 4.5 (h - 1)

D. y = 3.5x + 1

E. y = 4.5 + 20x

Options A and C

Step-by-step explanation:

To have a unit rate of change of 4.5 means to have the slope at 4.5

A. y = 62 + 4.5x GOOD

B. c = 4.5 + 3h - 1 WRONG

C. c = 12 + 4.5h - 4.5 GOOD

D. y = 3.5x + 1 WRONG

E. y = 4.5 + 20x WRONG

Answer: Options A and C
