Answer
$ŷ =137.7x-4599$
Work Step by Step
In MINITAB, enter the Size 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 (Size)
$ŷ =137.7x-4599$
