    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/equation-of-a-line-1?topic=developmental-math-2 and a few of the other videos he does with finding the equation of a line
