Answer:
1. It increases at 0-15 minutes
2. The rate of change is 3 and I got it by using the formula; [tex]\frac{rise}{run}[/tex] 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; [tex]\frac{rise}{run}[/tex] 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.
Step-by-step explanation:
1. As you can see the line is going up which means its increasing.
