It is known that the points M (−14) and D (−36) are symmetric. Specify the coordinate of the center of symmetry, point X.

Between the points M (−14) and D (−36) the distance is equal to: | -36 | – | -14 | = 22
To find the center, you need to halve the distance. 22/2 = 11
The center lies at a distance of 11 from each point. -36 + 11 = -25 and -14-11 = -25
Answer: X (-25)
