Given xy = K + 13, X and Y () A. Negative proportion B. positive proportion C. out of proportion D. not sure

Given xy = K + 13, X and Y () A. Negative proportion B. positive proportion C. out of proportion D. not sure

Because xy = K + 13, when k is fixed, then K + 13 is also fixed, which is the "product" of X and y, so x and y are inversely proportional
