(\stackrel{x_1}{21}~,~\stackrel{y_1}{30})\qquad (\stackrel{x_2}{35}~,~\stackrel{y_2}{50}) ~\hfill~ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{50}-\stackrel{y1}{30}}}{\underset{\textit{\large run}} {\underset{x_2}{35}-\underset{x_1}{21}}} \implies \cfrac{ 20 }{ 14 } \implies \cfrac{10}{7}

Check the picture below.
