Answer 1

`~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ P(\stackrel{x_1}{10}~,~\stackrel{y_1}{2})\qquad T(\stackrel{x_2}{-16}~,~\stackrel{y_2}{-17}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left(\cfrac{ -16 +10}{2}~~~ ,~~~ \cfrac{ -17 +2}{2} \right) \implies \left(\cfrac{ -6 }{2}~~~ ,~~~ \cfrac{ -15 }{2} \right)\implies (-3~~,~~-7.5)`
