Since y varies inversely with x, we know that the equation for inverse variation is: y = k/x, where k is the constant of variation.
Given that when x = 7, y = 4, we can plug these values into the equation to solve for k:
4 = k/7
k = 28
Therefore, the equation for the inverse variation is y = 28/x.
Suppose the y varies inversely with x. Write an equation for the inverse variation. y = 4 When x = 7
