WebDirect proportionality. Given an independent variable x and a dependent variable y, y is directly proportional to x [1] if there is a positive constant k such that: The relation is often denoted using the symbols "∝" (not to be confused with the Greek letter alpha) or "~", with exception of Japanese texts, where "~" is reserved for intervals: (or )

WebDirect proportion or direct variation is a type of proportion in which the ratio of two quantities stays constant. Suppose a variable y varies directly with x, then it means that if x increases, y increases by the same factor. If x decreases, then there is a proportionate decrease in y also.
