#### Answer

1; binomial

#### Work Step by Step

The degree of a polynomial is the largest degree of all its terms.
For the polynomial $7x-.8$, the exponent on x is 1, so the degree of the first term is 1. The second term can be rewritten as $-.8x^{0}$, so the degree of the second term is 0.
Therefore, the degree of this polynomial is 1. The polynomial is a binomial because it has two terms.
