Q. In a direct variation, y=6 when x=2. Write a direct variation equation that shows the relationship between x and y.Write your answer as an equation with y first, followed by an equals sign.
Understand direct variation: Understand the concept of direct variation. Direct variation means that y varies directly with x, which can be represented by the equation y=kx, where k is the constant of variation.
Find constant of variation: Use the given values to find the constant of variation.We are given that y=6 when x=2. We can substitute these values into the direct variation equation to find k.6=k×2
Solve for k: Solve for the constant of variation k. To find k, we divide both sides of the equation by 2. k=26k=3
Write direct variation equation: Write the direct variation equation using the found constant of variation.Now that we know k=3, we can write the direct variation equation as y=3x.
