Question

The midpoint of CD is E(-1,0). One endpoint is C(5,2). What are the coordinates of the other endpoint?

Answer 1

How do you get that?

Answer 2

Let the x-coordinate of D be denoted by x while the y-coordinate of D be donated by y.
(x-1)/2=5 [after solving you should get x=11)
(y-0)/2=2 [after solving you should get y=4]
Hence coordinates of D is (11, 4)

Answer 3

Thanks!
