Answer 1

does it say a or b is a constant? if so, the polynomial is of degree 1. if not, I don't know.

Answer 2

The degree of a term is the sum of the exponents of all variables of the term.
The degree of the polynomial is the same as the degree of the term with the highest degree.
Remember that a simple variable such as x, a, b, y, etc. really is x^1, a^1, b^1, y^1, etc.
