WebInverse Variation. In Maths, inverse variation is the relationships between variables that are represented in the form of y = k/x, where x and y are two variables and k is the constant value. It states if the value of one quantity increases, then the value of the other quantity decreases. In our day-to-day life, we observe that the variation in ... WebSince k is constant, we can find k given any point by multiplying the x-coordinate by the y-coordinate. For example, if y varies inversely as x, and x = 5 when y = 2, then the constant of variation is k = xy = 5 (2) = 10. Thus, the equation describing this inverse variation is xy = 10 or y = . Example 1: If y varies inversely as x, and y = 6 ...
