Degree: 5; leading coefficient: 10
Option D is correct.
Step-by-step explanation:
We need to identify if is a polynomial function, then state its degree and leading coefficient or not.
- Polynomial
A polynomial is an algebraic expression containing two or more terms that have same variables but may have different exponents combined through mathematical symbol(+,-,*or/)
So, is a polynomial function
- Degree of polynomial
The degree of polynomial is the highest degree obtained by sum of all exponents of individual terms in the polynomial.
So, has highest degree 5
Degree = 5
- Leading Coefficient
The leading coefficient is the coefficient of first term of the polynomial.
So, has leading coefficient = 10
So, Leading coefficient = 10
So, Degree: 5; leading coefficient: 10
Option D is correct.

Answer:
y = 1/4x + 5
Step-by-step explanation:
The given line has a "rise" of -8 for a "run" of 2, so a slope of ...
m = rise/run = -8/2 = -4
The perpendicular line will have a slope that is the opposite of the reciprocal of this slope. Its slope will be ...
-1/m = -1/(-4) = 1/4
The equation you're looking for will have an x-coefficient of 1/4. The suitable choice is ...
y = 1/4x + 5 . . . . the third choice
