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.
