Step-by-step explanation:
A coefficent is a numerical or constant quantity placed before and multiplying the variable in an algebraic expression. Or in other words, the number being multiplied with the variable. For example, the 4 in 4x.
The expression is -3x + 1. If we go back to the definition, the coefficient is the number combined with the variable.
So the answer is -3.
