Answer:
The function best models the linear relationship is y = 12000x + 40000 .
Step-by-step explanation:
As given
A used car already has 40,000 miles on its odometer.
Let us assume that y represented the total miles travelled by the car.
As given
The average owner will drive 12,000 miles per year.
Let us assume that number of years be x.
Distance travelled in x years = 12000x
Thus
Total distance travelled by the car = Distance travelled in x years + Distance travelled already shown in odometer .
y = 12000x + 40000
Therefore the function best models the linear relationship is y = 12000x + 40000 .
