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.
