The cost of a taxi ride is a linear function of the distance traveled. If a 5-mile ride costs $12 and a 9-mile ride costs $14, which equation can be used to find the cost, c, for any distance, m, traveled?

Respuesta :

Here:

slope = (14-12)/(9-5) = 2/4 = 1/2

equation

c - 12 = 1/2(m - 5)

so answer is
a. c-12 = 1/2 (m-5)
