Solve linear equations by graphing (all of my equations don't have a Y value so do i just place a dot on the X line?)

1) -3x+2=-1
2) x+2=0
3) 4x-2=-2
4) x+2=x-1
5) x+4=3
6) x+1=x-7
7) 13x+2=11x-1
8) -9x-3=-4x-3
9) -x+2=-x+1

I think we need more information on what topic you are on in algebra at the moment. But my best guess would be to solve for x, and then place your answers on the x-axis. This would be questionable though, because you would get many 0=(some number), which would be answered as untrue. Question numbers 4, 6, and 9 would all be untrue. Other than that,
1) x = 1
2) x = -2
3) x = 0
4) 0 = -3 (untrue)
5) x = -1
6) 0 = -8 (untrue)
7) x = -3/2
8) x = 0
9) 0 = -1 (untrue)
