Answer
$ŷ =-0.130x+50.78$
Work Step by Step
In MINITAB, enter the Age values in C1 and in C2 enter the HDL Cholesterol 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 (HDL Cholesterol) and C1 is x (Age).
