At how many points can two lines intersect?

There are 3 cases of intersection of lines. In the first case, if 2 straight lines are parallel, then they do not intersect at all, that is, these lines do not have common points. In the second case, if the lines intersect, but do not coincide with each other, then they always intersect at 1 point. In the third case, if 2 lines coincide with each other, then they have an infinite number of points.
