Points A (-3.25) and B (2.65) are marked on the coordinate line. Find the coordinate of point M – the midpoint of segment AB.

The coordinates of the midpoint of the segment are found by the formulas x = (x1 + x2) / 2, y = (y1 + y2) / 2, where (x; y) are the coordinates of the midpoint of the segment M, (x1; y1) are the coordinates of the beginning of the segment A, (x2; y2) – coordinates of the end of segment B.

A (- 3; 25); x1 = – 3, y1 = 25;

B (2; 65); x2 = 2, y2 = 65;

x = (- 3 + 2) / 2 = – 1/2 = 0.5;

y = (25 + 65) / 2 = 90/2 = 45.

Answer. M (0.5; 45).
