Yes, all the answers written in pencil are correct.
Answer:
exact form: 13 over 6
decimal form: 2.16
mixed number form: 2/ 1 over 6
The rate of change for this function is 1/2.
In order to find the rate of change, you use the slope equation.
m (slope) = (y2 - y1)/(x2 - x1)
m = (4 - 2)/(9 - 5)
m = 2/4
m = 1/2
