Suppose that a y varies inversely with x, and y=0.2 when x=2. What is an equation for the inverse variation?
Standard Form of an Inverse Variation:
These are the values that are given to us,
and we know that it is an inverse variation. We can plug in these numbers into the standard formula of an inverse variation.
Now that we've used out values to find
Plug in your values into the variation, solve for k, make a new variation but plug in the value for k.
