2

8

0

Answer 1

@aaronq

Answer 2

What is y when x=-2? Use your graph.

Answer 3

Earth to @andy11 do you know how to read a graph?

Answer 4

Looks like this is gonna be a monolog. Take the difference between the two values of y at x=0 and x-2. This would be a subtraction.
Then divide the value you get from that subtraction by the difference (another subtraction of the two x values. Good luck my friend.

Answer 5

in case you don't know,
rate of change = change in y divided by change in x

the change in x for x = 0 to x = −2
is last x - first x, or in this case -2 - 0 = -2

so we know
\[ \text{rate of change } = \frac{\text{change in y }}{ -2} \]
now you need to find the y value when x is 0
and the y value when x is -2

can you do that ?
