Answer 2

`\bf \qquad \qquad \textit{direct proportional variation} \\\\ \textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby \begin{array}{llll} k=constant\ of\\ \qquad variation \end{array}\\\\ -------------------------------\\\\ \cfrac{m}{n}=4\implies m=4n\impliedby \begin{array}{llll} \textit{\underline{m} varies directly with \underline{n}} \end{array}`
