Answer:
[tex]\boxed {\frac{2}{1}}[/tex]
Step-by-step explanation:
Use the rise over run to help you find the rate of change of the following graph:
[tex]\frac{rise}{run}[/tex]
Since every point shows that it is going up, then it means that the numbers you going to have are going to be positive:
Rise = [tex]2[/tex]
Run = [tex]1[/tex]
[tex]\frac{rise}{run} = \boxed {\frac{2}{1}}[/tex]
So, the rate of change is [tex]\frac{2}{1}[/tex].
