Question

It is given that $x$ and $y$ are in direct proportion and the difference in $y$, when $x$ is $5$ and $13$, is $48$. Find the equation connecting $x$ and $y$. Find the value of $x$ when $y=72$. Source check: an unsigned difference of $48$ does not determine the sign of the constant. The positive answer assumes $y(13)-y(5)=48$.

Accepted Answer

(a) $y=6x$ or $y=-6x$. (b) Respectively, $x=12$ or $x=-12$.
