You can put this solution on YOUR website!
3x + y = 6
3x - y = 0
Re-write each equation in the slope-intercept formate (y=mx+b]
.
3x + y = 6 [solve for y]
y=-3x+6 [Graph]
.
The purpose of graphing the two equations is to find their common points. The lines cross at (1, 3)
.
3x - y = 0 [solve for y]
-y=-3x+0
y=3x[Graph]
.
