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)?
