Hey, I can't get how to do it.

Any advice will be appreciated.

Thank you

If ^B0 and ^B1 are the least-squares estimates for the intercept and the

slope in a simple linear regression model, show that the least-squares

equation ^y = ^ B0 + ^ B1x always goes through the point (x-bar; y-bar).

Hint: Substitute x for x in the least-squares equation and use the fact

that ^B0 = y-bar ^B1x
