Find the other endpoint of the line segment with the given endpoint and mid point.

1. Endpoint:(-1, 9), midpoint: (-9, -10)

2. Endpoint: (2, 5), midpoint: (5, 1)

3. Endpoint:(9, -10), midpoint: (4, 8)

• trig -

I will do the 2nd
You do the others the same way....

Let the other endpoint be (x,y)
(x+2)/2 = 5 and (y+5)/2 = 1
x+2 = 10 and y+5 = 2
x = 8 and y = -3
the other endpoint is (8,-3)
