Question

Find the midpoint of PQ

Answer 1

$\bf ~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ \begin{array}{ccccccccc} &&x_1&&y_1&&x_2&&y_2\\ % (a,b) &P&(~ -4 &,& -6~) % (c,d) &Q&(~ 8 &,& 2~) \end{array}\qquad % coordinates of midpoint \left(\cfrac{ x_2 + x_1}{2}\quad ,\quad \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left( \cfrac{8-4}{2}~~,~~\cfrac{2-6}{2} \right)\implies (2~~,~~-2)$
