Points M (-6.37) and K (1.53) are marked on the coordinate line. Find the B coordinate – the middle of the MK.

Given:

M (-6; 37)

K (1; 53)

B – middle of MK

Find: coordinates B.

Decision:

The coordinates B of the midpoint of the segment KM are found by the formulas:

xB = (xK – xM) / 2 = (1 – (-6)) / 2 = 7/2 = 3.5;

yB = (yK – yM) / 2 = (53 – 37) / 2 = 16/2 = 8.

Answer: B (3,5; 8).

Note: xK, xM, yK, yM are the x and y coordinates of points K and M.
