Final answer:
The correct description of the expression 3x - 2 is that 3x is the term with the coefficient, and -2 is the constant term.
Step-by-step explanation:
The expression 3x - 2 consists of two main parts. First, 3x is the term with the variable where 3 is the coefficient, and x is the variable. The coefficient is the number that multiplies the variable. Second, -2 is the constant term. A constant term is a term that does not contain any variables and has a fixed value. Therefore, the correct way to describe the expression 3x - 2 in terms of its parts is: 3x is the term with the coefficient, and -2 is the constant term.
