Intro to direct & inverse variation (video) Khan Academy
Direct variation is a variation in which the quotient of two variables is a constant. If the ratio between two quantities is constant, it means that one quantity varies directly as the other quantity, or the two quantities are in direct variation. In symbols, the direct variation formula is y=kx or k=y/x where k is the constant of … See more Using the concept of linear equations, the variables in direct variation are positive and so the graph of the variation can be seen on the first … See more What is the constant of variation, k, of the direct variation, y = kx, through (5, 8)? Through (-3, 2)? Solution The ordered pair (5, 8) represents an ordered pair of the format (x, y). It means that the value of x is 5 while that of y is 8. … See more Which relation is a direct variation that contains the ordered pair (2,7)? 1. y = 3.5x 2. y = 0.286x 3. y = 27x Solution The given ordered pair (2, 7) represents the generally ordered pair (x, y). This means that x = 2 and y = 7. … See more WebOct 29, 2024 · The equation above is the direct variation equation and will be explored in the next section.
