Parallel and Perpendicular Lines

What is the definition of parallel lines on a coordinate plane?

• Lines that intersect at one point and have different slopes.

• Lines that are equidistant from each other at all points and have the same slope.

• Lines that curve and meet at infinity.

• Lines that are perpendicular to each other.
