Answer 1

Explanation:

Answer 2

1. It increases at 0-15 minutes

2. The rate of change is 3 and I got it by using the formula;
`(rise)/(run)` to calculate. So the line went up 15 and right 5 times so it'll be 15/5 = 3

3. It stays constant from 15-35 minutes.

4.The rate of change is 0 because the rate of change for every horizontal line is 0.

5. It decreases from 35-45 minutes

6. The rate of change is -4 and I got it by using the formula;
`(rise)/(run)` to calculate. So the line went down -20 and right 5 times so it'll be -20/5 = -4

7. The rate of change is negative because the line is going down which means that the line is negative.

Explanation:

1. As you can see the line is going up which means its increasing.
