Inverse variations are a type of variations that are not linear and never touch neither axis. They, in a graph show a line that is not linear and never touches zero because it involves division. The form of equation in the inverse variations is normally y=k/x, x=k/y and k=xy. This is the main information about inverse variations.
In the graph this variation never touches the line. It is because this variation involves division and multiplication of changing variables, so it will never touch the axes. The division is almost never negative because this variation most of the times is related to measures and measurements of figures. So, when you see a line in a graph that will never touch the axes it is probably an inverse variation.
The equations of inverse variations show very clearly that it is not linear. The equation of linear variations shows constant slopes and x and y intercepts. In the equations of inverse variation the equation is not with a constant slope, x intercept nor y intercept. As you can see linear and inverse equations are very different.
