Can you show your work? You started with the 2 points, (1,2) and (2,3).... what did you do first?

y - (3) = 1(x - 2) y - 3 = 1x - 2 y - 3 = 1x - 2 -1x -1x -1x + y - 3 = -2 +3 +3 -1x + y = 1 1x - y = 1

I can try to help, but you should really post each question separately. It looks like you're offline now and I have to go do some other things, but just post it as a new question, and someone will help! :) You can always tag me if you want, and if I'm online I'll try to help.
