Researchers record the fuel consumption of a car y (in miles per gallon) at various speeds x (in miles per hour). Using software, they determine that the least-squares regression line of their data is y^=70.243−0.329x Use this to predict the fuel consumption of the car when it is moving at 20 miles per hour.
