Rate of change Flashcards | Quizlet – Which relation is a direct variation that contains the ordered pair (2, 7)? d If y varies directly as x, and y is 180 when x is n and y is n when x is 5, what is the value of n?Algebra 2 Chapter 2 2.1 Relations and Functions 4 C: Direct Variation Some quantities have a relationship where the ratio of corresponding values is constant. One type of relationship is called "direct variation" and occurs when y kx k or y x where k is the "constant of variation".The relation or y = seven-halves x is direct variation. Step-by-step explanation: Given: The ordered pair = (2, 7). Now, to get the direct variation: As (2,7) lies on it. So, direct variation means. Now, Now, to get the direct variation: or y = seven-halves x. Therefore, the relation or y = seven-halves x is direct variation.
