Answer
$ŷ =-2055x+20976$
Work Step by Step
In MINITAB, enter the age values in C1 and in C2 enter the price values.
Select Stats -> Regression -> Regression -> Fit Regression Model
Enter C2 in "Responses" and C1 in "Continuous Predictors"
The least-squares regression line ($ŷ =b_1x+b_0$) will be shown in "Regression Equation", where C2 is $ŷ $ (price) and C1 is $x$ (age).
