Linear algebra doesn't have many preconditions - so being used to math texts is much more important for it than having some pre-knowledge.

Easiest to start will be either Linear Algebra done right by Axler or Linear algebra done wrong by Treil - try both, they take very different approaches to introducing the subject, so one of them may be compatible with you.

After finishing either of these I heartily recommend you Finite-Dimensional Vector Spaces by Halmos - it's way more abstract, so I cannot recommend it as first introduction to LA, but it proves its results in very beautiful and a bit uncommon way. It's probably my favourite book from undergrad.
