The equation of the regression line relating the number of miles per gallon on the highway and that in the city for some cars is
Predicted Highway MPG = 7.792 + 0.9478 City MPG
a)
Slope=0.9478
Value of the slope is larger than 0. This indicates that there is positive correlation between city MPG and Highway MPG. A change of 1 in city MPG will give a change of 0.9478 in Highway MPG.
It means that for each additional city MPG,the Highway value goes up by 0.9478 MPG.
b)
Intercept=7.792
The value of intercept is the predicted value of y when x=0, or for a car which has city MPG 0. That is not statistically meaningful.
So it is inappropriate to interpret intercept because no car get 0 MPG in the city.
