Best ResponseYou've already chosen the best response.0If you notice, there are two points that are marked on the graph. One is (1,3) the other is (5,0). Use those two points to find the slope.

Best ResponseYou've already chosen the best response.0replace m with 1/2 which is the slope. Replace x1 with 1 and y1 with 3 because you are using the point (1,3)
