Suppose that when a system of linear equations is graphed, one line completely overlaps the other line. which statement is correct?

There are certain cases that need to be taken into consideration:
1. If the lines intersect at one point the solution that fits all equations is exactly that point.
2. If the lines do not intersect at only one point the system has no solution because the lines 
3.  If the system of equations intersects completely overlaps the other line we say that we have an infinite number of solutions that fits the equations.
