Answer 3

C is the only answer where the slope=2/3. We can prove this by counting (when you have to show your work, use the distance formula, though, most teachers don't like the response "I counted the spaces." :D ). one of the points, (-3,0) --> (0,-2), another of the points. So the slope is accurate ONLY on problem C, which means that you now have your answer.
