Question

Use the graph below for this question:

What is the average rate of change from x = −5 to x = −4?

Answer 1

The average rate of change is the slope. We can see from that graph that when x=-5, y=1
So it is the coordinate (-5,1) and when x=-4, y=-4 so the other point is (-4,-4)
Use the formula \(\large \frac{y2-y1}{x2-x1}\), can you do that?

Answer 2

yeah ill do it real quick and let you know what i got. it will take a minut

Answer 3

ok i got 3

Answer 4

\(\large\frac{-4-1}{-4+5}=\frac{-5}{1}\)

Answer 5

it doesnt show what you put. it says math processing error

Answer 6
