Let's make the midpoint of the two points and be the point . In other words, the midpoint is

If we do that, then....

and

So in this case, we know that the midpoint is (3,-4) and we're given one endpoint of (-4,-6). So this means that and

In other words, , , , and

So plug these values into the formulas
and to find the point

I'll let you do that. Let me know if you still need help.

m is the midpoint, so it is halfway between r and s

in the x-direction; m is 7 from r (3 - -4), so s is 7 from m ___ or 10 (3 + 7)

in the y-direction; m is 2 from r (-4 - -6), so s is 2 from m ___ or -2 (-4 + 2)

so s is (10,-2)
