Question

TThe mid-point of a line segment is M(- 3, 2) . One end-point of the segment is P(1,-3). Find the coordinates of the other end point.

Answer 1

If the other endpoint is Q, then we have
Q-M = M-P
Q = 2M-P = 2(-3,2)-(1,-3) = (-6,4)-(1,-3) = (-7,7)

Answer 2

sorry

Answer 3

Q-PQ=2M-P=2(-3;2)-(-6;4)-(1;3)=(77)
