1; 6

#### Work Step by Step

A term is composed of a numerical coefficient and a variable. The numerical coefficient is the constant in front of the variable of a term. The degree of a term is the power to which the variable of the term is raised.
Therefore, the numerical coefficient of $y^{6}$, which can be rewritten as $1\times y^{6}$, is 1.
The degree of $y^{6}$ is 6, because the variable $y$ is raised to a power of 6.
