I have two quick questions about Mathematica. Firstly, I am wondering how to create/draw an augmented matrix (a matrix with a line seperating it into two parts). For example:

[4 5 6 | 1]
[5 2 6 | 2]
[3 6 3 | 2]

Secondly, is there any way to come up with one possible solution to problem with infinite solutions. For example:

u = {1, 2, 3}; (* any old vector *)
v = {a, b, c};

Solve[Dot[u, v] == 0]

I am looking for any value of v that is not the zero vector ({0, 0, 0}) that is perpendicular to u (so their dot products are equal to 0).

It's easy enough to do on paper, but I can't seem to find a way to make Mathematica do it. Thank you very much.
