Some help please?

What is the coefficient of the term of degree 1 in the polynomial

The coefficient is the number in front of the variable.

For example:

2x           2 is the coefficient

5y           5 is the coefficient

The degree is the exponent of a variable.

For example:

y         "y" has an exponent of 1, so the degree is 1

The variable that has an exponent of 1 is 3x, so the coefficient of the term is 3

3

Step-by-step explanation:

Degree 1 is x¹ or x

Term in x is 3x

Coefficient is 3

your answer is b.
