T-statistic question

[LBJ6]

So my teacher decided to throw us a bonus for extra homework points...I've taken a look at this, and could use a bit of help getting started.

It's a proof problem, and I need to prove that the T-statistic for beta...best way for me to show you is to post an image. Any help is much appreciated, I understand you guys aren't in the business of giving straight answers, I could really just use as much help as possible here though! Thanks!

Note that the use of adjusted R^2 ...i.e. (N -2) is being used in the relationship.
