Question

Find the midpoint M of the line segment joining thee Point S =(6,-7) and I =(-8,3)​

Answer 1

$\bf ~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ S(\stackrel{x_1}{6}~,~\stackrel{y_1}{-7})\qquad I(\stackrel{x_2}{-8}~,~\stackrel{y_2}{3}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left( \cfrac{-8+6}{2}~~,~~\cfrac{3-7}{2} \right)\implies \left( \cfrac{-2}{2}~~,~~\cfrac{-4}{2} \right)\implies (-1~,~-2)$
