Question

What are the coordinates of the midpoint of the line segment with endpoints (−4, 4) and (−2, 2)?

Answer 1

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