**MathGuru**, Monday, April 5, 2010 at 12:35amIf you need to show the work by hand, you can develop the regression equation in the following format:

predicted y = a + bx

...where a represents the y-intercept and b the slope.

To get to that point, here are some formulas to calculate along the way.

To find a:

a = (Ey/n) - b(Ex/n)

Note: E means to add up or to find the total.

To find b:

b = SSxy/SSxx

To find SSxy:

SSxy = Exy - [(Ex)(Ey)]/n

To find SSxx:

SSxx = Ex^2 - [(Ex)(Ex)]/n

I hope this will help get you started.
