Question

If a point lies in xy-plane then what is its z-coordinate?​

Answer 1

Answer:

the z coordinate will be zero

Answer 2

Answer:

0

Step-by-step explanation:

If a point lies on xy plane, its coordinates are of this form :- (x, y)

Now, if we represent this point on a 3-D Cartesian Plane, the coordinates will be (x, y, 0).

So, the z - coordinate is 0.
