WebDirect variation is represented as follows: Y = KX, where K is the constant of proportionality. The direct variation graph is a line through the origin. Inverse Variation. The quantities are said to be in inverse proportion if: … 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 … 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 quadrant of a coordinate plane.

WebSep 13, 2024 · Given equation : y=5/2x. Solution: In order to graph direct variation equation, we need to make a table of different values of x and y. We need to plug some values of x's in equation to get values of y's. … WebSince k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.
