Explanation / Answer

Solution4

For linear model it is not best fit as R sq=0.2724

For Quadratic model it is R sq=.696

Go for Quadratic model

Average price=-665.82*distance^2+28637*distance-989.25

For X=13

Average price=-665.82*13^2+28637*13-989.25

average price=258768.17

average price=258768
