A) y=12.0876+26.2719x

B) y=26.2719+12.0876x

C) y=26.2719+12.3889x

D) y=12.3889+26.2719x

2. An automotive engineer computed a least squares regression line for predicting the gas mileage (y) in miles per gallon of a certain vehicle from its speed (x) in miles per hour. The result is y= -0.13x + 33.94

Predict the gas mileage when the vehicle is traveling at 45mph. Round to one decimal place.
