Find the coordinates of the missing endpoint if B is the midpoint of A C . A ( − 4 , 2 ) , B ( 6 , − 1 )

Answer 1

C is (16,-4) the other end point when the midpoint B is (6,-1) and the other endpoint is A (-4,2)

it might help to plot the points

C's x coordinate is (6 - -4) +6 = 16

C's y coordinate = (-1-2)-1 = -4

actually, it really seriously helps plotting the points, to see what's going on
