# Direct Variation

Direct variation stands as a fundamental concept in mathematics, highlighting the straightforward relationship between two variables. In this mathematical model, as one quantity changes, the other follows suit in a consistent and proportional manner. The simplicity of direct variation lies in its linear nature, where the graph of such relationships forms a straight line passing through the origin. Understanding direct variation is crucial in various fields, providing a concise and predictable framework to analyze and interpret real-world scenarios, making it an indispensable tool in mathematical applications and problem-solving.
