Parallel lines are everywhere equidistant, which means that all such perpendicular segments have the same length. Example: Find the distance between the parallel lines l and m with the equations y = 2x + 1 and y = 2x – 4, respectively. Exercises Find the distance between each pair of parallel lines with the given equations. 1. y = 8 y = –3 2. y = x + 3 y=x–1 3. y = –2x y = –2x – 5
