Answer:
The other endpoit has this cordinadetes (11, 11).
Step-by-step explanation:
Midpoint (MD) (Xm, Ym)
Xm = 5
Ym = 2
Xm of the Midpoint: Xm = X1 + X2/ 2
Ym of the Midpoint: Ym = Y1 + Y2/2
We can say that S is (x1, y1), so x1 = -1 and y1 = -7
Then:
Xm = -1 + x2/2
5= -1 + x2/2
10 = -1 + x2
x2 = 11
Also:
Ym = -7 + y2/2
2 = -7 + y2/2
4 = -7 + y2
11 = y2
