Question

What is the midpoint of (6,-6) and (-4,1)

Answer 1

`~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ (\stackrel{x_1}{6}~,~\stackrel{y_1}{-6})\qquad (\stackrel{x_2}{-4}~,~\stackrel{y_2}{1}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left(\cfrac{ -4 +6}{2}~~~ ,~~~ \cfrac{ 1 -6}{2} \right) \implies \left(\cfrac{ 2 }{2}~~~ ,~~~ \cfrac{ -5 }{2} \right)\implies \left( 1~~,~~-2(1)/(2) \right)`
