Question

Another question, Given the coordinate of one endpoint of AB and its midpoint, M, Find the coordinates of the other endpoint. A(-5,1) M(1,-1) How do I do this?

Answer 1

Solution 1
A->M x-coordinates +6 y-coordinates -2
M->B should be x-coordinates +6 y-coordinates -2
(7,-3)

Solution 2
midpoint formula: average of each coordinates
(-5+x)/2,(1+y)/2)=(1,-1)
M(x,y)=(7,-3)

Answer 2

Thank you!
