Final answer:
Position in three-dimensional space is specified by three coordinates on a set of Cartesian axes.
Step-by-step explanation:
In three-dimensional space, positions are specified by three coordinates on a set of Cartesian axes, and the displacement of one point from another is given by:
(Ax, Ay, Az) = (x2 − x1, V2 - V₁, Z2 — Z1).
