Question

find the Midpoint of the segment A (5,8) and B (-1,-4)

Answer 1

$\bf ~~~~~~~~~~~~\textit{middle point of 2 points } \\\\ A(\stackrel{x_1}{5}~,~\stackrel{y_1}{8})\qquad B(\stackrel{x_2}{-1}~,~\stackrel{y_2}{-4}) \qquad \left(\cfrac{ x_2 + x_1}{2}~~~ ,~~~ \cfrac{ y_2 + y_1}{2} \right) \\\\\\ \left( \cfrac{-1+5}{2}~~,~~\cfrac{-4+8}{2} \right)\implies \left(\cfrac{4}{2}~,~\cfrac{4}{2} \right)\implies (2~,~2)$

Answer 2

Let M = midpoint

M = [(-1 + 5)/2, (-4 + 8)/2]
