Answer 1

`\bf ~\hspace{11em}\textit{\Large constant of proportionality}\\ \begin{array} \cline{1-2} \stackrel{minutes}{x}&\stackrel{cupcakes}{y}\\ \cline{1-2} 70&40\\ 49&28 \\ \cline{1-2} \end{array}~\hspace{2em} \stackrel{slope}{ m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{28}-\stackrel{y1}{40}}}{\underset{run} {\underset{x_2}{49}-\underset{x_1}{70}}}\implies \cfrac{-12}{-21}\implies \cfrac{4}{7}`
