What is Indirect Variation?
Back
Indirect variation (or inverse variation) is a relationship where one variable increases as the other decreases. It can be expressed as y = k/x, where k is a non-zero constant.

What is Joint Variation?
Back
Joint variation occurs when a variable varies directly with the product of two or more other variables. It can be expressed as z = kxy, where k is a non-zero constant.
