Find the coordinates of the other endpoint, t. please help!!--8,7-Lets break it down by coordinates,......
The midpoint of st is m =(-1,1) . One endpoint is s = (6,-5) . Find the coordinates of the other endpoint, t. please help!!

-8,7

Let's break it down by coordinates, lets start with the x coordinate. One endpoint is 6 and the midpoint is -1. That means the other end point has to have the same distance from the midpoint. Since the distance between 6 and -1 is 7 the second endpoint must be also 7 units away so it's -8. Now for the y coordinate. The midpoint's y coordinate is 1 and the endpoint's y coordinate is -5. That distance is 6 so the second endpoint's y coordinate must also be 6 units away. 6 away from 1 is 7. So the other endpoint is (-8,7).

The other end point is the same distance from the midpoint, just the other direction

from (-1,1) to (6, -5) is 7, -6

now subtract that from (-1,1)

-1-7 = -8
1 - -6 = 7

(-8, 7)
