Answer:
4/5
Explanation:
Slope(m) = (y2-y1)/(x2-x1)
Pick two points on your graph that are closest to clear values. (By that I mean you shouldn't pick points that aren't obvious unless you have to.)
For instance, I see the points (-2,0) and (3,4) to be clear; so we don't have to approximate anything.
You could plug these in in a any order but I'm going to let Point 1=(-2,0) and Point 2=(3,4). So:
m=(4-0)/(3--2)=(4/5)
Slope=4/5
