Help asap!! The graph of a function includes the points (4, 5) and (21, 39) . What is the rate of change of the function ?

A 0.5

B 2

C 17

D 34

Will give brainliest

The rate of change, slope, m is

m=(y2-y1)/(x2-x1), we have points (4,5) and (21,39) so

m=(39-5)/(21-4)

m=34/17

m=2

So the rate of change is 2

Step-by-step explanation: i searched it up on actually

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !
