Fill in the blanks:A line is parallel to xy-plane if all the points on

1.	Fill in the blanks:A line is parallel to xy-plane if all the points on the line have equal ________.
Answer» z-coordinate Explanation: If a line is parallel to xy plane, perpendicular distance of each and every point on line from xy plane remains. ∵ z-coordinate of a point gives its perpendicular distance from xy plane. This implies that z-coordinate of every point must remain the same.

Answer»

z-coordinate

Explanation:

If a line is parallel to xy plane, perpendicular distance of each and every point on line from xy plane remains.

∵ z-coordinate of a point gives its perpendicular distance from xy plane.

This implies that z-coordinate of every point must remain the same.
