Graph problems!!!

posted by .

Ok. so i'm supposed to find the coordinates of a line using the slope intercept method but i don't understand it!!! can some one PLEEAASE help me? also i'm supposed to graph a line using the same method and they give me the coordinates oly its in an equation form that i need to solve only i don't know how. heres the coordinates. please help me unscramble it all!

y= 3/2*(x) + 3

2y= -(x) + 2

oh, um, whoops, i kinda forgot one of the problems. its the one where i'm supposed to find the coordinates of a line. i know the coordinates, but i don't know how to how to get them. here they are.

y= -(x) + 2
PLEASE HURRY!!!! thanx. :-)
