Question 59605: I need some help on this problem, Can someone show me what the graph looks like. I am very lost.
I need to solve the system by graphing:
x + y = 3
x + y = -1

Thanks so much,

You can put this solution on YOUR website!
x + y = 3
x + y = -1
Re-write each equation in the slope-intecept format (y=mx+b)
.
x+y=3
y=-x+3 [graph]
.
x+y=-1
y=-x-1 [graph]
.
The purpose of graphing two lines is to find the point of intersection. These lines do not intersect, so they do not have any points in common.
