Direct Variation - Free Math Help
https://www.freemathhelp.com/direct-variationHow do I Recognize Direct Variation in an Equation? The equation y x = 6 y x = 6 states that y varies directly as x, since the ratio of y to x (also written y:x) never changes. The number 6 in the equation y x =6 y x = 6 is called the constant of variation. The equation y x =6 y x = 6 can also be written in the equivalent form, y =6x y = 6 x.
Direct Variation - ChiliMath
www.chilimath.com › direct-variationSolution: Divide each value of y by the corresponding value of x. The quotient of y and x is always k = - \,0.25. That means y varies directly with x. Here is the equation that represents its direct variation. Here is the graph. By having a negative value of k implies that the line has a negative slope.
