SL Core 2.1
Two lines are parallel when they have the same gradient m and they do not intersect:
In this case, the system of equations formed by the two lines has no solutions.
If the lines have the same gradient and they intersect, then they must be the same line. In this case the system will have infinitely many solutions.
