In Direct, Joint, and Inverse Variation, our instructor begins with direct variation and the constant of variation before moving into graphs of constant variation. Joint variation with three variables is next with inverse variation and its graph. Last are proportions which make it easier to solve direct and inverse variations. Extra examples at the end make sure you understand all the concepts.
Use values given in a problem to find the constant of variation. The use this value and other values to find the missing value.
