what is direct variation​

Direct variation describes a relationship between two variables where one variable is a constant multiple of the other. It can be written as:y = kxwhere k is a constant. In this case, if x increases, y increases proportionally, and if x decreases, y decreases as well.The graph of a direct variation is a straight line that passes through the origin (0, 0). For example, if y = 3x , when x = 2 , then y = 6 . Overall, direct variation shows how two quantities are related in a consistent, linear way.
