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

I only really need to know HOW to do it, I'd rather know than have the answer please, thanks!

Find the distance CE. Now you know half the distance of CD. Add distance distance CE to E and you will get the final coordinate.

If the line is not straight I usually separate the distances into distance in x-direction and distance in y-dicetion respectively.
