WebTo be more "geometrical" about it, if y varies directly as x, then the graph of all points that describe this relationship is a line going through the origin (0, 0) whose slope is called the constant of variation. That's because each of the variables is a constant multiple of the other, like in the graph shown below: Key concepts of direct ... WebNote down a direct variation equation that relates x and y with each other. Solution: Let us use the direct variation formula y = kx. Replace y with 72 and x with 8. ... Explain the characteristic of the direct variation graph. Ans. The line will show a y-intercept at the origin (0,0) and a slope equal to the variation constant k. Thus, the g...

How to Write a Direct Variation Equation Algebra Study.com

WebThe direct variation equation is of the form y = kx, where x and y are variables and k is the constant of proportionality. The direct variation equation states that y varies directly with x, which essentially means that as x increases or decreases, y also increases or decreases proportionally. Figure 02: The Direct Variation Equation y = kx 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. chronic bad breath remedies
