Question
hey,i dont at all know how to graph
4x+2y=6
x-y=3
I dont even know if its one question or two, its written exactly like that so it could be either, im not sure.  thanx  

Answer
You have two straight lines.  It only takes two points to graph a straight line.  Re-write the 1st equation as
2x = 3-y
then you can put in a value for y, calculate x, and plot.
For example, two points are (1,1) and (-1,5)
for the 2nd line, x = 3+y so two points are (1,4) and (5,8).
