In math, direct variation is a proportional linear relationship between two variables that can be expressed as the equation y = kx, where y and x are variables and k is a constant.

Jul 23, 2025 · Direct variation is a mathematical relationship between two variables in which one variable is a constant multiple of the other. In other words, when one variable changes, the …

A direct variation is a proportionality relationship in which two quantities follow a direct relationship. This implies that an increase (or decrease) in one quantity leads to a …

Direct variation is a proportional relationship between the x x -coordinate (an independent variable) and the y y -coordinate (a dependent variable), where the ratio between the x x …

May 19, 2025 · In algebra, understanding relationships between variables is critical. One of the simplest but most powerful such relationships is direct variation. At its core, direct variation …

Welcome to our math tutorial! In this video, we’ll explore the concept of Direct Variation — a fundamental topic in algebra that shows how two quantities change together in a constant ratio...

Direct variation refers to a relationship between two variables where when one variable increases the other also increases by the same factor. Conversely, when one variable decreases, the …

A relationship in which one quantity is a constant multiplied by another quantity is called direct variation. Each variable in this type of relationship varies directly with the other.

A direct variation, also called direct proportion is a relationship between two variables x and y that can be written as y = kx, k ≠ 0. This situation occurs when the ratio of two variables is constant.

We say that y y varies directly with x x if y y is expressed as the product of some constant number k k and x x. If we isolate k k on one side, it reveals that k k is the constant ratio between y y …
