You can put this solution on YOUR website! What is a super imposed line and what are unique solutions?
If you have a system of two linear equations that are really the same equation
the two graphs will be two lines, one superimposed on the other, and the solution for the system of equations will be the set of all points on the
line.
-----------
If you have a system of two linear equations that have different line graphs
and those lines are not parallel, the solution for the system will be the
unique point of intersection of the two lines.
