show work as to how you found the answer

(2,8) and (-2,10)

y₂ - y₁     used to find the slope
x₂ - x₁

plug in the coordinates
10-8 = 2     all equals -1/2
-2-2 = -4     m=-1/2

plug one of the coordinates and the slope into y=mx+b, and solve
8=-1/2(2)+b
8=-1+b
9=b

Final  y = -1/2x + 9

Ithink you're supposed to multiply 12.50 which is how much he makes per hour and then multiply it by each number then add whats left togrther and there's your answer
