Direct Variation - Definition and Examples
www.basic-mathematics.com › direct-variationTherefore, y = 6x is the direct variation equation When x = 4, y = 6 × 4 = 24. So you can make 24 cupcakes Not every equation represents a direct variation or a direct proportion. Examples of equations that are direct variations: y = -4x y = 5x y = (-4/6)x y = (2/3)x y = 100x Equations that are not y = -4x + 2 y = 5x -5/7 y = (-4/6)x + 7 y = (2/3)x + 3
Direct Variation - ChiliMath
www.chilimath.com › direct-variationDivide 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.
