Answer
The expression is a monomial.
Variables: $x$ and $y$
Coefficient: $-2$
Degree: $3$
Work Step by Step
RECALL:
(1) A monomial is a product of a constant and some variable/s whose exponents are nonnegative integers.
(2) The degree of a monomial is the sum of the exponents of its variables.
The exponents of the variables are 1 and 2, which are nonnegative integers.
Thus, the expression is a monomial.
The monomial has:
Variables: $x$ and $y$
Coefficient: $-2$
Degree: $3$
