Find the coordinate of the midpoint of the segment AB, if A (-6.5), B (12.5).

By condition, points A (-6; 5) and B (12; 5) are given.

To find the midpoint of a segment on a plane, the following formulas are used:

Xc = (Xa + Xb) / 2;

Yc = (Ya + Yb) / 2.

Imagine that point C is the midpoint of a line segment with coordinates Xc and Yc. Then, Xa and Ya are coordinates of point A (Xa = -6; Ya = 5), and Xb and Yb are coordinates of point B (Xb = 12; Yb = 5). Now let’s substitute all these values into the formulas:

Xc = (-6 + 12) / 2 = 3;

Yc = (5 + 5) / 2 = 5.

As a result, the coordinates of point C (the midpoint of the segment) are 3 and 5.

Answer: 3; five.
