Parallel lines have the same slope while the slope of perpendicular lines are negative reciprocals and... Parallel and Perpendicular Lines. Parallel lines have the same slope and will never intersect. Parallel lines continue, literally, forever without touching (assuming that these lines are on the same plane).
