Homework Help: Linear Algebra Question - Two Planes

  1. Sep 11, 2009 #1
    1. The problem statement, all variables and given/known data

    My question is:

    Isn't it possible for two planes to have one solution? Geometrically, what if their edges were touching and that was the extent of their intersection?

    What's the 'edge' of a plane? I thought planes were unbounded and didn't have 'edges'?

    Oh. Right. I forgot that went infinite. The darn diagrams make it look like they have edges!

    Tough to draw a picture of a plane without edges. Try to sympathise with the illustrators and forgive their lapses.
