By using the midpoint formula, we find that the coordinates of the point B are B(x, y) = (- 7, - 5).
Herein we know the coordinates of the midpoint and one end of the line segment AB. The location of the missing point, that is, the other end of the line segment A, can be found by using midpoint formula:
M(x, y) = 0.5 · A(x, y) + 0.5 · B(x, y)
(- 6, - 1) = 0.5 · (- 5, 3) + 0.5 · B(x, y)
(- 6, - 1) = (- 2.5, 1.5) + 0.5 · B(x, y)
(- 3.5, - 2.5) = 0.5 · B(x, y)
B(x, y) = (- 7, - 5)
By using the midpoint formula, we find that the coordinates of the point B are B(x, y) = (- 7, - 5).
