\bf \begin{array}{ccccccccc} &&x_1&&y_1&&x_2&&y_2\\ % (a,b) &&(~ (2)/(3) &,& (4)/(7)~) % (c,d) &&(~ (2)/(3) &,& (11)/(7)~) \end{array} \\\\\\ % slope = m slope \implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{(11)/(7)-(4)/(7)}{(2)/(3)-(2)/(3)}\implies \cfrac{(7)/(7)}{0}\implies \cfrac{1}{0}\impliedby un de fined
