Answer:
(6, 4, -6)
Step-by-step explanation:
The midpoint of two points is half-way between their x-, y-, and z-values.
For the x-coordinate,
(x₂ + x₁)/2 = (4 + 8)/2 = 12/2 = 6
For the y-coordinate,
(y₂ + y₁)/2 = (-2 + 10)/2 = 8/2 = 4
For the z-coordinate,
(z₂ + z₁)/2 = [-9 + (-3)]/2 = -12/2 = -6
The coordinates of the midpoint are (6, 4, -6).
