WebApr 16, 2011 · "The difference between the values of x and y is not what dictates whether the variation is direct or inverse. What is important is the factor by which they vary. WebThis becomes our constant of variation, thus k = - \,3 k = −3. The equation of inverse variation is written as, This is the graph of y = { { - \,3} \over x} y = x−3 with the points from the table. Example 3: Given that y y varies inversely with x x. If x = - \,2 x = −2 then y = 14 y = 14. a) Write the equation of inverse variation that ...
