Question

What is the midpoint of the segment?

Answer 1

The midpoint of a segment $A(x_A;\ y_A);\ B(x_B;\ y_B)\\\\M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)$

A(-12;-3); B(3;-8)

$M_{AB}\left(\dfrac{-12+3}{2};\ \dfrac{-3+(-8)}{2}\right)\to M_{AB}\left(\dfrac{-9}{2};\ \dfrac{-11}{2}\right)\to M_{AB}(-4.5;-5.5)$
