Using the concept of linear equations, the variables in direct variation are positive and so the graph of the variation can be seen on the first …
WebIf yes, write an equation to represent direct variation. Solution: 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. WebCOMBINED VARIATION Sometimes direct, inverse, and/or joint variation occurs within the same situation. When quantities vary in more than one way, we include all relationships in one equation.
