The midpointMof line segmentABhas coordinates (- 3,4). If pointAis the origin, (00), what are the coordinates of pointB.

MY WORK:

I used the distance formula to find the distance from point A to the midpoint. I found the distance to be 5 units from point A to the midpoint and of course, this means the distance to point B is 10 units. However, I was not able to find the coordinates of B. How do I find the coordinates of B without the need of graphing paper?

I also used the midpoint formula but got no where.

Thanks
