The ends of the segment AB have coordinates: a) A (-8), B (4) b) A (-13), B (6) What is the coordinate

The ends of the segment AB have coordinates: a) A (-8), B (4) b) A (-13), B (6) What is the coordinate of the midpoint of this segment M.

The x_M coordinate of the point M, located in the middle of the segment AB, the ends of which have coordinates x_A (point A) and x_B (point B), we find by the formula:

a) x_M = (x_A + x_B) / 2 = (-8 + 4) / 2 = -4 / 2 = -2;

b) x_M = (x_A + x_B) / 2 = (-13 + 6) / 2 = -7 / 2 = -3.5.
