Question

PLEASE HELP!Find the coordinates of the other endpoint when you are given the midpoint and one of the endpoints.
P1	M	P2
(10, 6)	(-4, 8)	( , )

anonymous · Answer

the distance between the midpoint and the first point is the same as the distance between  the midpoint and the last point

anonymous · Answer

so then it woudl be 3?

anonymous · Answer

(10 + x) /2 = -4  for x coordinate

hero · Answer

Yeah, jimmy rep has it. And take the same approach to find the y coordinate

anonymous · Answer

then check it with the distance formula to make sure that you have the correct points
