Perpendicular line equations.I've completed a few of these with no problem but I am stuck on: Aloha Nui means Goodbye. #2 20051206 00:58:08
Re: Perpendicular line equations.The perpendicular line would be: Aloha Nui means Goodbye. #3 20051206 02:26:06
Re: Perpendicular line equations.You got the gradient right, because to find a perpendicular gradient, you divide 1 by the original gradient. Why did the vector cross the road? It wanted to be normal. #4 20051206 02:27:07
Re: Perpendicular line equations.Thankyou mathsy! Aloha Nui means Goodbye. #5 20051206 02:30:55
Re: Perpendicular line equations.Perpendicular lines slopes always share a negative inverse relationship. Last edited by irspow (20051206 02:32:22) #6 20051206 02:52:09
