Using the Equation (Interpolation)- Ans

Use Eq Interpolation (video/mp4)

As you can see from the video we get    Approximately  63,634.6 miles

Using the Equation (Extrapolation)

Using your regression equation predict the number of miles on the car when it is 11 years old.

Using the Equation (Extrapolation)-Ans

Use Eq Extrapolation (video/mp4)

As you can see from the video we get    Approximately 125,976.4 miles

Using the Equation (With Solving)

Using your regression equation predict the age of the car when it has 135,000 miles on it.
