Question

In a direct variation, y = 18 when x = 6. Write a direct variation equation that shows therelationship between x and yWrite your answer as an equation with y first, followed by an equals signSubmit

Answer 1

$\begin{gathered} y=kx \\ \text{where:} \\ k=\text{constant of proportionality} \\ y=18,x=6 \\ 18=6k \\ k=\frac{18}{6} \\ k=3 \\ so\colon \\ y=3x \end{gathered}$
