$\bf ~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ A(\stackrel{x_1}{-7}~,~\stackrel{y_1}{4})\qquad B(\stackrel{x_2}{3}~,~\stackrel{y_2}{-4}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left( \cfrac{3-7}{2}~~,~~\cfrac{-4+4}{2} \right)\implies \left( \cfrac{-4}{2}~,~\cfrac{0}{2} \right)\implies (-2~,~0)$
