Answer:
m = -1.25
Step-by-step explanation:
Slope = (Y2-Y1) = (9-14) = (-5) = -1.25
(X2-X1) (7-3) (4)

Part a: Option D 18 feet per second
Part b: increasing
Solution:
Height 
Part a: To find the average rate of change for h(t) between t = 0 and t = 2.
Substitute t = 0 in h(t).

h(0) = 3
Substitute t = 2 in h(t).
h(2) = 39
Average rate of change formula:

Here, a = 0 and b = 2.



= 18
Average rate of change = 18 feet per second
Option D is the correct answer.
Part b:
This means height of the ball is increasing for 0 < x < 2.
1/(x+5) because the (x-2) is canceled from both the numerator and denominator of the equation.
