Question 43908: please help me! Solve by graphing. if necessary, estimate answer to nearest half unit.
x - 2y = -6
y = -3/2x - 1

1. x - 2y = -6
2. y = -3/2x - 1
First of all it is easier to graph in y=mx+b form. The second equation is already there but we need to get the first one to that point and all that take is a little rearranging
x-2y=-6==>-6+x=2y==>-3+1/2x=y==>y=1/2x-3
Now you have the following equations:
1. y=1/2x-3
2. y=-3/2x-1
On the first equation go to point (0,-3) go up one and to the right two and draw a line through those two points.
On the second equation go to point (0,-1) go down three to the right two and draw a line through that point.
