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 Web20 Questions Show answers. Q. In a direct variation, y=39 when x=3. Find the value of y when x=2. Q. y varies directly with x, and y is 16 when x is 32. Which equation represents this situation?

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.
