Answer:
A: 1
B: 2
C: 1/2
Explanation:
To find the vertical change, look at how many units point A and point B are away from each other vertically, which is 1 unit.
To find the horizontal change look at how many units point A and point B are away from each other horizontally, which is 2 units.
The rate of change is the same as the slope of the graph, so the answer is going to be the vertical change divided by the horizontal change.
