Final answer:
In the given polynomial X + 9, the coefficient is 1, the constant is 9, and the degree is 1. Therefore, the polynomial is a linear polynomial.
Step-by-step explanation:
In the given polynomial X + 9, the coefficient is 1 (the number multiplying the variable), the constant is 9 (the number without a variable), and the degree is 1 (the highest power of the variable).
Therefore, the name of this polynomial is linear polynomial because it has a degree of 1.
