\[m=\frac{ y2-y1 }{ x2-x1 }\]
does it help?

Yes, that would give you the slope. Then you pick one of the points and that slope and substitute the x-value of the point you choose for x1 and the y-value of the point you choose for y1 into: y-y1 = m(x-x1)
This then gives y - 2 = 4/3 (x-3) or y -(-2) = 4/3 (x-0) which simplifies to y + 2 = 4/3 x

Thank you. So, ow would you convert y - (-2) = 4/3(x - 0) to standard form?

To simplify it, would I use the distributive property, or would it be y + 2 = 4/3 x like gcuwagirl said?

So, to clarify it would be: y + 2 = 4/3x

Okay, I know that part, but now I'm trying to convert it to standard form. Could you help me with that?
