Direct variation k formula

WebIf a proportionality constant is put, then the direct variation formula is given as, x = ky. Or, x/y = k. Here, “k” is the constant of proportionality. This equation represents that when two directly proportional quantities are divided, the resultant value is always a constant. 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 ...
