Point slope form
y-y1=m(x-x1)
m=slope
(x1,y1) is a point
(-5,-1)
x1=-5
y1=-1
m=-5/4
y+1=-5/4(x+5)
y=-5/4x-29/4

Answer:
y = 25 (for x less than/equal to 12)
y = 25 + 1.25(x - 12) for x > 12
For x = 20
y = 25 + 1.25(20 - 12)
y = 25 + 10
y = $35
The answer if we go by solving only for "r" Will be -2, in other words r=-2
