Answer
y=15
Work Step by Step
Our equation for an inverse variation is y=kx or xy=k. We will use the second form of the equation to solve for k.
We use the ordered pair (3,5) to solve for k, from which we know that x=3 and y=5.
3×5=k
15=k
So, k=15
Therefore, our equation for the inverse variation is y=15/x or xy=15
Using the first form of the equation, y=15/x, we can use the x value of the second order pair to find our missing y value.
y=15/1
y=15
