Proof of formula?

Is there any reasonable, clear explanation(demonstration, proof??) of the
formulas for the standard error of the slope of the least squares
regression line? The text I use suggests using "some algebra using rules
for variances." I've tried several approaches but wound up going in
circles. I'm at the point of thinking that it's so obvious I'm missing
something, or too complicated for a novice statistician to see.

Thanks,
