Jonah is drawing up plans for a bicycle ramp using a coordinate grid. He plots the vertices of the ramp at points R(0, 4), M(0, 0), and P(16, 0). Write a proportion to verify that the slope of the ramp is the same at a different location. Use the points A(4, 3), B(4, 1), and C(12, 1).

y=1/4x-4

step-by-step explanation:

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
