Answer:

2

Explanation:

To find the average rate of change, we use:


(changeofy)/(changeofx) =rate ofchagne

To find this lets look at the graph.

We see that at x=2, y=-3, and at x=3, y=-1.

The change of y is the first y coordinates minus the second, which in this case is:

-3-(-1)=-2

Change is the absolute value of the 1st and 2nd y. So its really a change of 2, not -2.

Our change of x falls under the same formula, being:

2-3=-1, but really being 1.

Now to plug this into our first formula:

2/1=2

So the rate of change is 2.

This seems to be your first answer.

Hope this helps!
