Answer 1

(3, 1.5)

Explanation:

Answer 2

`\bf ~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ (\stackrel{x_1}{-5.5}~,~\stackrel{y_1}{-6.1})\qquad (\stackrel{x_2}{-0.5}~,~\stackrel{y_2}{9.1}) \qquad % coordinates of midpoint \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left( \cfrac{-0.5-5.5}{2}~~,~~\cfrac{9.1-6.1}{2} \right)\implies \left( \cfrac{-6}{2}~~,~~\cfrac{3}{2} \right)\implies \left(-3~,~1(1)/(2) \right)`
