$y = \frac{10}{x}$ or $xy = 10$

Work Step by Step

Our equation for an inverse variation is $y = \frac{k}{x}$ or $xy = k$. We will use the second form of the equation to solve for k. $4\times2.5 = k$ $ 10 = k$ $k = 10$ Therefore, our equation for the inverse variation is $y = \frac{10}{x}$ or $xy = 10$
