What are the leading coefficient, constant term and degree, if any, of the algebraic expression -7?

a. leading coefficient: 7: constant term: 7: degree: 1
b. leading coefficient: -7: constant term: -7: degree: 0
c. leading coefficient: 7; constant term: 7: degree: 0
d. none, expression is not a polynomial

D

Step-by-step explanation:

This isn't an algebraic expression and it definitely doesn't have any coefficients; nonetheless leading coefficients. A coefficient is basically the variable in an algebraic expression (ex. In the algebraic expression y = Mx + b, the leading coefficient would be "M". A constant term is something I honestly forgot, so don't take my word for it, but I believe it is "x", and the degree is an exponent that isn't in the simple algabraic expression, but could be in the algebraic expression; y = Mx^2 + b)

where's the diagrams?
