geno... I think you had a mistake.

The formula for inverse proportion is x= k/y.

From the x and y values we were given, we can find out that 2=k/4.

We can figure out that k=8.

Now the equation: Since we know k, we can plug in k as x, and y as 1 from the given value.

x=8/1.

Therefore, x will be equal to 8.
