If 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 yintercept 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.
