Answer:
m = rise/run = 1/5
Explanation:
There are two lines here, but only one, the blue line, has a positive slope. Our work boils down to calculating that slope. It is m = rise/run. Two points on the blue line are (0, 1) and (5, 2) (both of which sit on intersections of grid lines). From (0, 1) to (5, 2), x is seen to be increasing by 5 and y by 1, and so the slope here is
m = rise/run = 1/5
