Polynomial division would be the way I'd do it. The equation of the asymptote drops out immediately.

How would I do this with the algebra?

Makes no difference. You just have a's and b's there rather than actual numbers. Your asymptote will be a function of a and b.

E.g. (ax+b)/x becomes a + (b/x)
