Graph the direct variation equation y -1/2

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 WebJan 5, 2016 · yes it is a direct variation equation and constant of variation (k ) =0.5 when 2 quantities vary directly this can be expressed as follows y prop x to make this into an equation we have to introduce k , the constant of variation. rArr y = kx compare this to y = 0.5 x and so k = 0.5
