    Stumped!

    Teds Car Rental charges a fixed charge and so much per mile. Tara rented a car from Teds. She drove 150 miles and paid 65 dollars. Susan rented a car from Teds and drove 350 miles and paid 125 dollars. Determine a linear function that Teds uses for its charges.

    (150, 65)

    (350, 125)

    y - y_1 = m(x - x_1)
