Question

stack C D with bar on top has endpoints -3,4 5,2 What are the coordinates of its midpoint? ( -1,1), ( -2,2), (1,3), (4,3)

Answer 1

`\bf ~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ C(\stackrel{x_1}{-3}~,~\stackrel{y_1}{4})\qquad D(\stackrel{x_2}{5}~,~\stackrel{y_2}{2}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left(\cfrac{5-3}{2}~~,~~\cfrac{2+4}{2} \right)\implies (1,3)`
