Question 420783: x + 3y = 4
2x - y = 8
slove and graph
3x + y = -5
x - 2y = 3
slove and graph
2x + y = -4
x - 2y = -7
slove and graph
x + 3y = 7
-x + y = -3
slove and graph

You can put this solution on YOUR website!
What you do is you get them into the y=mx+b. So make them equal to y.
take the 2x-y=8
Subtract 2x
-y= -2x+8
Divide by -1
y=2x-8
Slope is 2
y intercept is -8
