There is one solution. When
graphing the lines, we observe that there is a point of intersection.

There is an infinite number of
solutions. When graphing the lines, we observe that there are infinitely many
points of intersection. The lines intersect at every point, so they are

There is not a solution. When
graphing the lines, we observe that there is not a point of intersection. The lines are parallel. Parallel lines never cross.
