Answer by tutorcecilia(2152) (Show Source): 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.
