Answer:
The missing end point is (-15,-16)
Explanation:
Mathematically, we have the formula for the midpoint as follows;
(x,y) = (x1 + x2)/2, (y1 + y2)/2
(x,y) = (-10,-6)
(x1,y1) = (-5,4)
(x2,y2)= (?,?)
(-10,-6) = (-5 + ?)/2, (4 + ?)/2
(-5 + ?)/2 = -10
-5 + ? = 2(-10)
-5 + ? = -20
? = -20 + 5 = -15
(4 + ?)/2 = -6
4 + ? = 2(-6)
4 + ? = -12
? = -12 - 4 = -16
So we have the missing coordinates as;
(-15,-16)
