Function A
x y
7 21
8 24
9 27
Function B
the picture.
Which statement best compares the rate of change of the two functions? (1 point)
The rate of change of both functions is 2.
The rate of change of both functions is 3.
The rate of change of function A is greater than the rate of change of function B.
The rate of change of function B is greater than the rate of change of function A.

Sorry I can't get the picture in...
I think the answer is B.) but I'm not so sure...
f(A) ... y = 3 x ... straight line ... slope of 3 ... through the origin
the slope is the rate of change ... (change in y) / (change in x)
f(B) ... can you find the slope from the picture
the slope is the rate of change ... (change in y) / (change in x)
f(B) ... can you find the slope from the picture
