Does every linear realtionship is a variation?

Not every linear relationship is a variation, but every variation is a type of linear relationship. A linear relationship describes a consistent change, often represented by a straight line, while variation specifically refers to a proportional relationship, such as direct or inverse variation. In direct variation, one variable is a constant multiple of another, while in inverse variation, one variable is inversely proportional to another. Thus, while all variations are linear, not all linear relationships imply a strict variation.
