The midpoint of segment AB is P(0, 4). If the coordinates of B are (-2, 3), then the coordinates of A are
⇒ Therefore by Midpoint Formula we have,
⇒ and y
Finding the coordinates of the end of A:
⇒ Finding x-coordinate:
⇒
⇒ x2 = 2
Finding y-coordinate:
⇒
⇒ 8 = 3 + y2
⇒ y2 = 8-3
⇒ y2 = 5
Therefore the coordinates of the end of A are (2, 5).
