Graph ΔACG with vertices A(1, 4), C(3, 2), and G(1, -2), and ΔBCF with vertices B(2, 1), C(3, -2), and F(2, -2). Then write a proportion comparing the rise to the run for each of the similar slope triangles and find the numeric value.
The plans for a set of stairs are shown below. Using points X and Z, find the slope of the line down the stairs. Then verify that the slope is the same at a different location by choosing a different set of points.
