A used car already has 40,000 miles on its odometer. The average owner will drive 12,000 miles per year.

Which function best models the linear relationship?

y = 12,000x + 40,000

y = 40,000x + 12,000

y = 52,000x + 12,000

y = 12,000x - 40,000

Think in terms of a straight line in "slope-intercept" form: y=mx+b.

When we first encounter this used car, it already has 40000 miles "on the clock." If 12000 represents the number of miles driven per year, then additional miles are represented by 12000x. With this info in mind, choosing the correct answer should be straightforward.
