#11 - Inverse Variation Review - Chris Long | Laabri

Inverse and direct variation can be easy to mix up.

With inverse variation, the x times the y is always the same number. That is the constant of variation (a), so the equation that represents the relationship looks like:

null

With direct variation, the y divided by the x is always the same number. That is the constant of variation (a), so the equation that represents the relationship looks like:

null

If the relationship between the x- and y-values is anything else, it does not represent direct or inverse variation!

Tell whether the table represents direct variation, inverse variation, or neither. If it is direct or inverse variation, write the equation.
