I think you have a typo on your regression page (http://people.revoledu.com/kardi/tutorial/Regression/OLS.html) about 3/4 of the way down, just be fore the example, you say: Notice that (a=summation) is actually equivalent to (slope = summation) by simple algebra. I think that you should either have \"a\" in both places or \"slope\" in both places. I think you actually mean \"a\" in both places.

Thanks for your report. Both are the equation of slopes. I fixed the text so that it becomes clearer.
