Question 297381: Indicate which of the following sets of lines are parallel,perpendicular,or neither.Show your work and explain why you chose the answer you did.21.
(a) y=2x-5,y=2x+5
(b) 3x+y=5,-x+3y=6
(c)3x+y=5,x+y=3
I am really confused and don't even know how to work this out(I've looked in the book) PLEASE help....THANKS VERY MUCH! =)
p.s. They only give a line this big to explain why I chose the answer I did.________________________
