Answer:
Constant rate of change is 9
Step-by-step explanation:
To find the constant rage of change we pick 2 points from the graph
points (0,0) and (1,9)
Rate of change is the slope
[tex]slope =\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]slope =\frac{9-0}{1-0}=9[/tex]
Slope = 9/1
Constant rate of change is 9
points (0,0) and (1,9) represent 9 units up from (0,0) and 1 units the right
