Find the missing endpoint if K is the midpoint of LM.
2) K(-4, -6) and M(-7, -2); Find L.

L is at point (-10, 1)

Explanation:

-4 is -3 poins away from -7, so add -7 and -3 to get -10. -6 is 4 points away from -2, so add -2 and 4 to get 1. (normally -2 + 4 is 2, but since it's a graph, you have to include point 0) sorry if my explanation doesn't make a whole lot of sense lol, just how I look at it. Hope this helps! :)
