$\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{11})\qquad (\stackrel{x_2}{7}~,~\stackrel{y_2}{9}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{9}-\stackrel{y1}{11}}}{\underset{run} {\underset{x_2}{7}-\underset{x_1}{2}}}\implies \cfrac{-2}{5}$

Since you can spend $48 so you can buy 16 items in either ways . let x be for hot dogs and y for hamburgers.
8x+20y=48
20x+4y=48
6x+21y=48
22x+13y=48
