If one end of a line segment is (4, 4) and midpoint is (-2,2), find the co-ordinates of the other end.

Soloha48 [4]

Answer:

-8,0

Step-by-step explanation:

From one end of a segment to the midpoint, it takes -6x to get to the midpoint. Based on that, you can go another 6 over the y graph and get -8 for x.

For y, the segment goes from 4 to 2 (a -2 over the x graph). you can infer then that the other end will be 0.
