Direct Variation

Work Step by Step

A quick way to recognize direct and inverse variation is to ask, "as x goes up in value, what does y do?" If y goes up, then it is a direct variation. If y goes down, then it is an inverse variation. In this case, as you buy more pounds of chicken, then the price would go up. Since both your x value and your y value increase together, this scenario represents a direct variation.
