@coachohdee The regression equation he is using is y = a+bx you need to solve for a in order to create the equation. a = the mean of the y-values, plus b (which he solved for and got 32.8788), times the mean of the x-values.
The equation you would see in statistics books would be y^ = b0+b1x

Whats y-bar?

@t0myuri It's the mean of the Y values.

b0= ybar -b1xbar

Clear video, but at the end, I don't really understand why it's the intercept+slope(x).
