Answer:
4
Step-by-step explanation:
Take two points from the graph. One appears to be (40,20) and another appears to be (50,60).
Slope is the rise over run, or the difference of the y values over the difference of the x values. The difference between 60 and 20 is 40, and the difference between 50 and 40 is 10, so 40/10, which simplifies to 4.
