How do you determine if 2 lines are parallel or perpendicular?
Find slope for both lines. If the slopes =, then the lines are parallel. If the slopes do not =, then multiply them. If the answer (product) = -1, then the lines are perpendicular. If product is not = -1, then the lines are neither parallel nor perpendicular.
