graph 3x+4y=8
----
You need 2 points:
Let x = 0, then y = 2
Let y = 0, then x = 8/3
------------------------------
Plot(0,2) and (8/3,0)
---------------------------
Draw a line thru them.
That is the graph you want.

To graph a linear function, like 3x%2B4y=8, all you need to do is determine 2 points, plot them and connect them with a straight line. Choose easy to calculate and plot points that are not too close together. x=0 and/or y=0 are often useful.
For x=0, 3x%2B4y=3%2A0%2B4y=0%2B4y=4y=8 ---> y=2, giving us the point (0,2).
For x=4, 3x%2B4y=3%2A4%2B4y=12%2B4y=8 ---> 4y=8-12=-42 ---> y=-1, giving us the point (4,-1).
