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

@563blackghost can you help?

Its either A or D, i dont know):

ronndjaia · Answer

the correct answer is y=12,000x+40,000

RawlsK29 · Answer

Since, they drive 12000 each year so would you not subtract that from 40000

ronndjaia · Answer

because you will take the average miles and add the # of miles the car already has on it's odometer and no you do not subtract you need to add
