Answer

The answers are: \begin{align} 9a^3: &\color{red}{\text{Coefficient is 9 and Degree is 3}}\\ -4a^2: &\color{red}{\text{Coefficient is -4 and Degree is 2}} \end{align}

Work Step by Step

To determine the coefficient of a term, identify the part of the term which is the constant factor (usually a number). To determine the degree of a monomial, identify the number of variable factors in the monomial. \begin{align} 9a^3: &\color{red}{\text{Coefficient is 9 and Degree is 3}}\\ -4a^2: &\color{red}{\text{Coefficient is -4 and Degree is 2}} \end{align}
