Solve the equation by graphing.
2x-3y=12
3y-2x=-12
Graph is attached.
The lines are the same, so there are infinite solutions, and this is dependent.

Solve the equation by graphing.
3x-y=4
3x-y=0
Graph is attached.
The lines are parallel and never meet, so there are no solutions. This is "inconsistent".
