the definition of inverse variation. If y y varies inversely with x x, then there is a constant k k, such that: y=k\cdot\frac {1} {x}, \quad k eq0 y = k ⋅ x1, k = 0. k k is called the constant of proportionality, or the constant of variation. Notice that as x x increases (or decreases) by some factor, y y (decreases or increases) by the same ... Solving a Direct Variation. The formula y = kx is used to solve a direct variation. If the proportionality constant needs to be determined, divide y by x to get the answer. If k is known and either x or y must be found, these values can be replaced into the equation above to discover the unknown value.The formula for direct variation is y = kx y = k x, where k k is the constant of variation. y = kx y = k x. Solve the equation for k k, the constant of variation. k = y x k = y x. Replace the variables x x and y y with the actual values. k = −4 −5 k = - 4 - 5. Dividing two negative values results in a positive value. k = 4 5 k = 4 5. Direct variation is a phenomenon where two quantities change together and depend on each other. Direct variation happens when two variables maintain a constant ratio, meaning that changes in one variable directly impact the other.
