Two variables x and y are said to be in direct variation with each other if you can write them in the form y = K * x. The value of y varies directly corresponding to the value of x. Y is said to be directly proportional to x. WebSolution: Divide each value of y y by the corresponding value of x x. The quotient of y y and x x is always k = - \,0.25 k = −0.25. That means y y varies directly with x x. Here is the equation that represents its direct variation. Here is the graph. Having a negative value of k k implies that the line has a negative slope.
