Yeah, so when you find the slope, you can put that in for m. Since you already know two points, you can pick one of them, for example 2,3 into the equation. So you get 3 = 2x (what you got for m) + b then you just solve for b

so y=2x+7 would be the final answer?

It looks like you understand it, but if you want more insight, try http://www.khanacademy.org/video/equationofaline1?topic=developmentalmath2 and a few of the other videos he does with finding the equation of a line
