parallel lines never intersect.
Since the lines that intersect are the equations, if they intersect once they have one solution.
Coplanar lines can intersect an infinite amount of times.
None. Parallel lines do not intersect in Euclidean geometry.
It depends on how you define "ways" and how you define "lines" and how you define "intersect" and what kind of geometry you're talking about, but in Euclidean geometry, lines either never intersect, or they intersect at a single point, or they can intersect at all points within the lines.
