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 :

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

[tex]\frac{y}{x}=\frac{8}{2}[/tex]

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

[tex]\begin{gathered} \frac{y}{x}=\frac{8}{2} \\ \frac{y}{x}=4 \\ y=4x \end{gathered}[/tex]

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