\textit{internal division of a segment using a fraction}\\\\ A(\stackrel{x_1}{-1}~,~\stackrel{y_1}{-3})\qquad B(\stackrel{x_2}{5}~,~\stackrel{y_2}{-4})~\hspace{8em} (8)/(9)\textit{ of the way from A to B} \\\\[-0.35em] ~\dotfill


(\stackrel{x_2}{5}-\stackrel{x_1}{(-1)}~~,~~ \stackrel{y_2}{-4}-\stackrel{y_1}{(-3)})\qquad \implies \qquad \stackrel{\stackrel{\textit{component form of}}{\textit{segment AB}}}{\left( 6 ~~,~~ -1 \right)} \\\\[-0.35em] ~\dotfill\\\\ \left( \stackrel{x_1}{-1}~~+~~(8)/(9)(6)~~,~~\stackrel{y_1}{-3}~~+~~(8)/(9)(-1) \right)\implies \left( \cfrac{13}{3}~~,~~-\cfrac{35}{9} \right)
