please correct answer ​

Answer 1

Answer:

An inverse variation can be expressed by the equation xy=k or y=kx . That is, y varies inversely as x if there is some nonzero constant k such that, xy = k or y=kx where x≠0 and y≠0 .

A direct variation, also called direct proportion is a relationship between two variables x and y that can be written as y = kx, k ≠ 0. This situation occurs when the ratio of two variables is constant. When y = kx, we say that y varies directly with x. When z = kt, we say that z varies directly with t.
