Question 48127: We were told to solve these systems by graphing but, on the graph he has a place for six points it is mapped out as:
x y1 y2
0 0 0
0 0 0
My first problem is x + 2y = 4
x + 2y = -2
My solutions were x = (0,2) (4,0)
y = (-4,1)(0.-4)
How do i graph this where do I place the numbers on the graph.

Before doing any substitutions, always solve for y. Doing so yields and . Because the slopes are exactly the same, that means the lines are parallel. If you substitute 0 for x in both equations you get y=2 for the first equation and y=-1 for the second equation. The graph is:
