Final answer:
The degree of the polynomial 6 - 8y - y⁷ is 7, and the leading coefficient is -1.
Step-by-step explanation:
The degree of a polynomial is the highest power of the variable in the expression. In the polynomial 6 - 8y - y⁷, the term y⁷ (y to the seventh power) has the highest power, making the degree 7.
The leading coefficient is the coefficient of the term with the highest degree, which in this case is -1, as the term y⁷ can be written as -1*y⁷.
