Identify Variable Power: Identify the highest power of the variable in the polynomial.In the polynomial −2r+7, the variable r has the highest power of 1, since it is equivalent to r1.
Determine Polynomial Degree: Determine the degree of the polynomial. The degree of a polynomial is the highest power of the variable present in the polynomial. Since the highest power of r is 1, the degree of the polynomial −2r+7 is 1.
