Difference between two numerical values of a variable quantity.
Mathematical model that best describes the differences between the coordinate values of the points in the Cartesian graph of a relationship.
Educational note
The term “variation” is sometimes used as a more concise way of referring to a “relationship of variation” of a certain type. For example, some authors write “The graph of a direct variation is…” instead of “The graph of a relationship of direct variation is…”
