Question

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)
4. Find the point that is one-fourth of the way from (2, 4) to (10, 8).

Answer 1

So base on your question that ask to provide and end point of the four statement you give:
1.Endpoint(-1,9), midpoint:(-9,-10)  - (-17, -29)
2.Endpoint(2,5), midpoint(5,1) - (4,5)
3.Endpoint(9,-10), midpoint(4,8)  -  i cant determine sorry
4.Find the point that is one-fourth of the way from (2,4) to (10,8) - also i cant.
