Quizplus · Accepted Answer

The midpoint of a line segment in three dimensions is found by averaging the x, y, and z coordinates of the endpoints. For the given points (-1,0,-7) and (-8,-5,-6), the midpoint is $\left( \frac{-1 + (-8)}{2}, \frac{0 + (-5)}{2}, \frac{-7 + (-6)}{2} \right) = \left( \frac{-9}{2}, \frac{-5}{2}, \frac{-13}{2} \right)$.
