Political intention: change methods to 'mastery' to improve learning for all. When a problem states that variable X varies directly as variable Y, we know that the relationship implied is . . X = . kY. And that the first step in solving the problem is to find the value of the constant of proportionality k. . Direct Variation. When we talk about a direct variation, we are talking about a relationship where as . x increases, . y increases. . or decreases at a . CONSTANT. . RATE. .. Direct Variation. Direct variation uses the following formula:. When the statement of a problem says that A varies directly as B or that A is directly proportional to B, the equation . . A = . kB. Is implied. . When the statement says that A varies inversely as B or that A is inversely proportional to B, the equation. Direct Variation. y varies directly as x if there is a nonzero constant, k, such that . y = . kx. *k is called the constant of variation. Plug in the two values you have and solve for the missing variable. Do Plants Show Variation in Traits? How Do We Know?. Review: Plant Traits and Variation.
