## since xy = k, and

0.2*2 = 0.4,

xy = 0.4

or,

y = 0.4/x

y = 1.8x

y = 0.4/x

x = y/1.8

y = x/0.4

How about this equation: y = 0.4 divided by x.

Why? Because y and x are inversely related, just like me and my ability to do my taxes. The more complicated the tax forms get (like a larger value of x), the less capable I am of understanding them (like a smaller value of y). It's a perfect inverse relationship!

Given that y varies inversely with x, we can write the equation as:

y = k/x

Where k is the constant of variation.

To find the value of k, we can use the given information:

When y = 0.2 and x = 2, we can substitute these values into the equation:

0.2 = k/2

To solve for k, we can multiply both sides of the equation by 2:

0.2 * 2 = k

0.4 = k

Now that we have the value of k, we can substitute it back into the equation:

y = 0.4/x

So, the equation for the inverse variation is:

y = 0.4/x
