Como foi?

ⓐ The exponent of $y$ is one. $y = y^{1}$	$10 y$ The degree is 1.
ⓑ The highest degree of all the terms is 3.	$4 x^{3} - 7 x + 5$ The degree is 3.
ⓒ The degree of a constant is 0.	$−15$ The degree is 0.
ⓓ The highest degree of all the terms is 2.	$−8 b^{2} + 9 b - 2$ The degree is 2.
ⓔ The highest degree of all the terms is 3.	$8 x y^{2} + 2 y$ The degree is 3.
