The coordinates of point T are (-3,-4). The midpoint of ST is (1,-8). Find the coordinates of S. It would be rlly nice if someone could help me out within the next 30 minutes!! Please and thank you.

Answer 1

If M is the midpoint,
S = M + (M-T) = (1,-8) + (4,-4) = (5,-12)

Answer 2

1.M(-1,-3) is the midpoint of ST. If the coordinates of A are (-3,2), find the coordinates of T.
Find the perimeter of a quadrilateral whose vertices are M(-2,2),I(5,2),L(4,-3) and K(-3,-3). What kind of a quadrilateral is MILK?
