the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
