Answer
Definitions: A term in an algebraic expression can be a constant, a variable or a product of constants and variables separated by the signs of addition $(+)$ or subtraction $(-).$ Examples: $27,\text{x},\text{xyz},\big(\frac{1}{2}\big)\text{x}^2\text{yz}$ etc. The expression $9 - ab + bc - ca$ consists of four terms, i.e, $9 - ab + bc$ and $-ca.$ The coefficient of the term is $9$ is $9.$ The coefficient of $−ab$ is $-1.$ The coefficient of $bc$ is $1,$ and the coefficient of $-ca$ is $-1.$
