Question 10 The graph of a function includes the points (4, 5) and (21, 39).
What is the rate of change of the function?
A
2
B
34
с
17
D
0.5

Step-by-step explanation:

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 dont

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
