Final answer:
The equation for the inverse variation is y = 24/x.
Step-by-step explanation:
In an inverse variation, the equation can be represented as y = k/x, where k is a constant. To find the equation for the given scenario, we can substitute the values of y = 4 and x = 6 into the equation and solve for k.
4 = k/6
Cross-multiplying, we get k = 24. Therefore, the equation for the inverse variation is y = 24/x.
