Answer:
2
Explanation:
Find 2 easy-to-read points. Points that easy to read are on the intersection of grid lines.
For example, choose (1, 1) and (2, 3).
slope = rise/run
rise = difference in y
run = difference in x
Start at point (1, 1). To go to point (2, 3), first you go up 2 units. The difference in y is 2, so the rise is 2. Then you go 1 unit to the right. The difference in x is 1, so the run is 1.
slope = rise/run = 2/1 = 2
Answer: slope = 2
