The slope of this line will be the same as the common ratio of any y-value to the corresponding x-value. So any equation of the form y = mx will represent a direct variation. The slope, m, is called the “constant of variation,” and some books use k instead of …

Write a direct variation equation that relates to x and y. Assume the y varies directly as x. Then solve. If y = -8 when x = -2, find x when y = 32. If y = 45, when x = 15, find x when y = 15. If y = -4 when x=2, find y when x = -6 . If y = -9 when x = 3, find y when x = -5 . The distance traveled varies directly with the time of travel.

To solve problem involving direct variation: Write an equation of the form y = kx relating the variables and the constant of proportionality, k. Determine a value for k, using a known relationship between x and y (a fact given to us in the problem)
Solving Direct Variation Problems
Direct variation is the formula y = kx and Indirect is y = k/x So basically if something varies directly (or jointly) it will be multiplied by the k, if it varies indirectly or inversely, k will be divided by it.
