Best ResponseYou've already chosen the best response.0parallel lines have the same slope and never meet. no intersections. perpendicular lines meet at 90 degrees. the product of the slopes = 1. intersecting lines have at least on set of values (x,y) that satisfies both equations. coincident lines are really just one line usually one is a factor of the other so all the (x,y) values work or both lines start by plotting the points to "see" what you have then Identify AB and CD and check the above conditions
