When you have a direct variation between two variables, this means that as one variable goes smaller, the other variable also goes smaller. When one variable goes larger, the other variable also goes larger.
Now, let's examine what happens in the equation
Notice as we increase
Looking from another perpective, as we decrease
This means that your equation is an inverse variation
