Question

What are the coordinates of the midpoint of the segment whose endpoints are A (1,6) and B (5,-2)?

Answer 1

`\bf ~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ A(\stackrel{x_1}{1}~,~\stackrel{y_1}{6})\qquad B(\stackrel{x_2}{5}~,~\stackrel{y_2}{-2}) \qquad % coordinates of midpoint \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left( \cfrac{5+1}{2}~~,~~\cfrac{-2+6}{2} \right)\implies (3~,~2)`
