Question

find the coordinates of the missing endpoint given that S is the midpoint. Problem: T(-4,3),S(-1,5)

Answer 1

the length of TS must be 3 in the x, and 2 in the y. Look at how I figured that out.

So the endpoint must be (2,7) check me.

Answer 2

-1 = (-4 + x) divided by 2 which results in x = 2

5 = (3 + y) divided by 2 which results in y = 7

Thus the missing point is (2,7).
