Question

the coordinates of point T are given. The midpoint of ST is (5,-8). Find the coordinates of point S.

18) T(10,18)

Answer 1

just note that S is the same distance from M (the midpoint) as T is.

So, for the x-coordinate, Mx-Sx = Tx-Mx
5-Sx = 10-5
5-Sx = 5
Sx = 0

Makes sense. We went from 10 to 5 to get from T to M. So, we have to drop another 5 to get to S: result is 0.

Now do the same for the y-coordinate

Answer 3

Given the coordinates of point T at (-5,6) and point X at (3,2). What is the coordinate for the midpoint of line segment TX?
