The midpoint of XY is point
M(—12, 5). If the coordinates
of X are (3, —3), what are the
coordinates of Y ?
----
Each coordinate of the midpoint is the average
of the corresponding endpoint coordinate.
----
Solve:
Let the coordinates of Y be (x,y)
---
(3+x)/2 = -12
3+x = -24
x = -27
----
(-3+y)/2= 5
-3+y=10
y = 13
---
Coordinates Y: (-27,13)
