Answer
A--III
B--I
C--II
Work Step by Step
Graph I has a line that goes through the points (0,-2) and (1,2). The slope of this line is $\frac{2--2}{1-0}$, or 4. The only line with a slope of 4 is B.
Graph II has a line that goes through the points (0,-2) and (2,0). The slope of this line is $\frac{0--2}{2-0}$, or 1. The only line with a slope of 1 is C. Thus, graph III has a slope of 1/4.
