In 3-dimensions that can easily occur, but in two dimensions, two lines will either intersect at one point, or be parallel and never intersect.

This may be observed physically by putting two straight edges on a flat surface. However you place them, the lines extended from them will either intersect or be parallel.

You can demonstrate this mathematically by seeing that there is one common solution point for set of two line equations, or none at all.
