Question

What is the midpoint of a segment whose endpoints are (–3, –6) and (6, –2)?

Answer 1

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