To find the constant of variation, we choose two pairs of values for x and y: (2,6) and (4,12). How to Find the Constant of Variation. Thus, the equation describing this direct variation is y = 3x. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = 3. Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. Substituting these values into the equation from step 2, we get: Solving … How to calculate the constant of variation | Math Solver. Example 2 Tell whether x and y are in a proportional relationship. m=ory = mx, where m is the constant of variation and m0 y=3x.

Make your own table and find at least three points to graph a line that represents the. Direct Variation - Algebra I - SparkNotes. For each direct variation, find the constant of variation.
