Answers: 1
![\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} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ (\stackrel{x}{-3},\stackrel{y}{2})\textit{ we also know that } \begin{cases} x=-3\\ y=2 \end{cases}\implies 2=k(-3)\implies \cfrac{2}{-3}=k](/tpl/images/0079/0747/a1070.png)
