      Direct, Inverse, and Joint Variation Notes and Examples Two or more quantities that are related to each other are said to vary directly, inversely, or jointly. All variation problems involve a constant of proportion, k., but whether the two quantities grow or decrease together determines what type of variation you will use.

      A direct variation is a situation in which two quantities increase or decrease at the same rate. A mechanic who is paid hourly knows that working longer means making more money. That's because his pay varies directly as the number of hours worked. As his hours increase, so does the amount of his paycheck.

      INVERSE VARIATION An equation of the form y=k x or xy=k k!0 is called inverse variation. In this situation, as the variable x increases, the variable y decreases and the reverse is also true. The graph is a curve that never touches either axis. Example The time it takes to travel a fixed distance varies inversely with the speed traveled. If it ...
