Answer:
The average rate of change is 10.
Step-by-step explanation:
Since the average rate of change is the slope of a line, you'd solve this problem by finding the slope.
First, you can start by using the [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] method.
Plug in the points (0,10) and (1,20).
[tex]\frac{20-10}{1-0} =\frac{10}{1} =10[/tex]
Therefore your answer is 10.
