Question

If a point is located above the xy-plane, then which

coordinate(s) must be positive?
O the y-coordinate
O the z-coordinate
O the x- and y-coordinates
the y- and z-coordinates

Answer 1

If a point is located above the xy-plane, the z-coordinate must be positive.

Step-by-step explanation:

If a point is located above the xy-plane, then the z-coordinate must be positive. The xy-plane is the plane formed by the x and y-axes in a three-dimensional coordinate system. Points above this plane have a positive z-coordinate, as the z-axis extends upward from the xy-plane.
