An inverse variation is a relationship between two variables in which the product of the variables is a constant. Mathematically, it is expressed as , where  is a non-zero constant.

 

Now let's analyze each of the given equations:

1. :

   - This equation is in the form of a linear equation with a slope of  and a y-intercept of . It does not match the form of an inverse variation equation.

2. :

   - This equation is in the form , where . When  increases,  decreases and vice versa, which is a characteristic of inverse variation. For example, if , then
