Hi Jessica, for each set of coordinates of a line segment, m = (a + b)/2, where m is the coordinate of the midpoint and a and b are the coordinates of the endpoints. Let's start with the x-coordinates. Then we have:

m = (a + b)/2

6 = (4 + b)/2

Now you can solve this equation for b, which is the x-coordinate of the other endpoint. Then use the same formula to do the same thing for the y-coordinates. Let me know if you have any trouble.
