Homework Help: Geometry

Posted by Supaman on Monday, February 18, 2008 at 1:21am.

Letting L1=ax+by+c=0
and L2=px+qy+r=0.

The equation of anyline passing through the intersection of L1 and L2 is

L1+kL2=0 where k is a variable depending on just how the actual line through the point is.

Can anyone prove this because all i get is 0=0.
