Jonah is drawing up plans for a bicycle ramp using a coordinate grid. He plots the vertices of the ramp at points R(0, 6), M(0, 0), and P(15, 0). Write a proportion to verify that the slope of the ramp is the same at a different location. Use the points A(5, 4), B(5, 2), and C(10, 2).

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.

step-by-step explanation:

answer is x<

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

(-5,-28)
