Answer
Therefore, our equation for the inverse variation is y=2.5/x or xy=2.5
Work Step by Step
Our equation for an inverse variation is y=k/x or xy=k. We will use the second form of the equation to solve for k.
1/2×5=k
2.5=k
So, k=2.5
Therefore, our equation for the inverse variation is y=2.5/x or xy=2.5
