Question

In a direct variation, y = 8 when x = 2. Write a direct variation equation that shows therelationship between x and y.Write your answer as an equation with y first, followed by an equals sign.Submit

Answer 1

First of all, we need to remember that in a direct variation, we have the following relationship between x and y:

`(y)/(x)=(8)/(2)`

Now, we simplify and make a cross multiplication and we have:

`\begin{gathered} (y)/(x)=(8)/(2) \\ (y)/(x)=4 \\ y=4x \end{gathered}`

The equation is y=4x, that is your answer.
