Question

JK has endpoints J(−5,4) and K(7,−10). Identify the coordinates of the midpoint of JK. Please help!!

Answer 1

$\bf ~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ J(\stackrel{x_1}{-5}~,~\stackrel{y_1}{4})\qquad K(\stackrel{x_2}{7}~,~\stackrel{y_2}{-10}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left( \cfrac{7-5}{2}~~,~~\cfrac{-10+4}{2} \right)\implies \left( \cfrac{2}{2}~~,~~\cfrac{-6}{2}\right)\implies (1,-3)$
