The inverse property of addition states that for any number a, its additive inverse (-a) is such that a + (-a) = 0. In this case, 9y is added to its additive inverse (-9y) to get 0, which satisfies the definition of the inverse property of addition. The inverse property of addition states that for any number a, there exists an additive inverse -a such that a + (-a) = 0. In this case, 9y and (-9y) are additive inverses of each other, resulting in a sum of 0. Therefore, the property illustrated is the inverse property of addition.
