Question

What are the coordinares of the point that si halfway between (4,1) and (-22,8)?

Answer 1

`~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ (\stackrel{x_1}{4}~,~\stackrel{y_1}{1})\qquad (\stackrel{x_2}{-22}~,~\stackrel{y_2}{8}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left(\cfrac{ -22 +4}{2}~~~ ,~~~ \cfrac{ 8 +1}{2} \right) \implies \left(\cfrac{ -18 }{2}~~~ ,~~~ \cfrac{ 9 }{2} \right)\implies (-9~~,~~4.5)`
