Curiosity gets the best of me. Do these people have books? I can't believe any textbook on algebra/pre-calc/analytic geometry wouldn't have this definition. A definition such as this one would also generally be in bold print, or separated from the rest of the text, etc, in order to demonstrate its significance. In other words, it shouldn't be all that difficult to find.

the slopes of parallel lines are equal

if A1,B1 are two lines perpendicular to each other than if

the slope of A1 is m

then slope of line B1 is -1/m

am i right?? - May 6th 2010, 08:59 AMHallsofIvy
Yes.
