Your equation simplifies to

**Case 1:**

**Case 2:**

so you have four rays, all with terminus at the origin (alternatively, two lines passing through the origin). See http://www.wolframalpha.com/input/?i...%28y+%2B+3x%29 - October 19th 2009, 01:26 AMPeleus
Any hints as to how it actually simplifies down to that? I'm not sure at what point I should be manipulating it to produce that result.
