The other endpoint is -5,-8.
A+ = segment C A
If endpoint J is at (4, 15) and midpoint L is at (1, 8) then endpoint K is at (-2, 1) Because (4-2)/2 = x and (15+1)/2 = y for midpoint (1, 8)
double the length
Assuming that you meant midpoint, it is a median.
a median is a line or segment with one endpoint as the midpoint, and the other end at the vertex. so start at a vertex and draw a straight line to the midpoint of the opposite side.
If you mean endpoint (6, 9) and midpoint (7, 6) then the other endpoint is (8, 3)
If you are only given one endpoint and a midpoint, you know what the middle of the line segment is. Since the midpoint is half of what the line segment's length is, all you have to do is find the distance between the endpoint given and the midpoint, then add that coordinate to your midpoint and get your other endpoint. For example: Endpoint A: (4,5) Midpoint: (6,8) Distance between: (2,3) Add (2,3) to (6,8) and get Endpoint B: (8,11).
Given only the midpoint you cannot.

The direction of missing endpoint is the same as the direction from the known end point to the midpoint. The distance from the midpoint to the missing endpoint is the same as the distance from the known end point to the midpoint. In coordinate geometry it is simple. If the known end point is (p, q) and the mid point is (r, s) then the missing point is (2r - p, 2s - q).
-- Find the distance between the endpoint and the midpoint.-- Double that distance to get the length of the complete segment.-- When you're finished, sit quietly for a moment and ponder the meaning of "midpoint".
Midpoint
A line segment has endpoints and a midpoint.
i have found the answer dont worry.
The other endpoint is -5,-8.
Yes, the median of a triangle is from a vertex to the midpoint of the side opposite the vertex.
