Oh, honey, the relationship of quantities is just like a dysfunctional family reunion - you've got addition, subtraction, multiplication, and division all fighting for attention. They all work together in their own special ways to give you the final answer. Just remember, they may not always get along, but they sure know how to make math interesting.
It shows a relationship among certain quantities.
Direct relationship: When two quantities increase or decrease together. Inverse relationship: When one quantity increases while the other decreases. Linear relationship: When the relationship between the quantities can be represented by a straight line. Nonlinear relationship: When the relationship between the quantities cannot be represented by a straight line.
The relations between quantities are stated by multiplicative relationship between the quantities.
an equation that expresses a relationship between two or more quantities
The answer depends on the quantities and the nature of the relationship. It can be a line-of-best-fit (or regression line), or a formula.
It is a non-linear or non-existent relationship between the two quantities.
