3x+2y=8

2y=-3x+8

y=-3/2x+4

4y=-6x+16

y=-3/2x+4

Both equations give you the same line. Easiest way to draw the line is to start out with your basic x,y coorindates. set x as zero in the equation: y=-3/2(0) +4; y=4. So your first point will be (0,4) (this is all you really need because you know the slop already, but to make it simple, calculate another point on the graph).

Next, set y as zero: 0=-3/2x+4; 3/2x=4; x=8/3. So your second point is (8/3,0)

Plot both points on the graph and connect the dots, and that should be your line.

Now do the same thing for the second question, except in number 2, the 2 equations are different and thus you will have 2 lines instead of one. Just work on one equation at a time using the same method as number 1.

6x+4y=16

2y=8-3x

y=(8-3x)/2

just put this at y-plase in 6x+4y=16

finally u’ll get x=0 y=4

2x+y=5

3x-y=10

y=5-2x <--- put this in 3x-y=10 3x-(5-2x)=10 3x-5+2x=10 5x=10+5 5x=15 x=3 y=5-2*3 y=-1
