Margie's car can go 32 miles on a gallon of gas, and gas currently costs $4$4 per gallon. how many miles can margie drive on $20$20 worth of gas?

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
