Question 288172: Draw any line l1 with slope -1. What is the slope of any line perpendicular to l1? Draw any line l2 perpendicular to l1. Answer by dabanfield(803) (Show Source):
You can put this solution on YOUR website! For a line L2 to be perpendicular to a line with slope -1 the slope of the perpendicular line must be the negative reciprocal of -1 which is -(1/-1) =
-(-1) = 1.
