Two functions, A and B, are described as follows:

Function A
y = 9x + 4

Function B
The rate of change is 3 and the y-intercept is 4.

How much more is the rate of change of function A than the rate of change of function B?

2

3

6

9
I believe the answer is either C or B but I am stuck

3 answers

functionA
y = 9x + 4 ---->rate of change = 9
functionB
y = 3x + 4 ----> rate of change = 3

so what do you think?

Um B.

No its c
