easy way to graph a straight line is to use the intercepts
for the first one:
let x=0, y = 3, (should be able to do this in your head)
let y = 0, x = 6
so you have two points, (0,3) and (6,0)
plot the points and join with a straight line
Do the same with the 2nd equation
it should look like this:

x+2y=6
2x+4y=32
how would i graph them and what would be my points?
