Question

which undefined geometric term is described as a location on a coordinate plane that is designated by an ordered pair $(x,y)$?
distance
line
plane
point

Explanation:

In geometry, a point is an undefined term. It has no size (no length, no width, no height). It is represented by an ordered pair \((x,y)\) on a coordinate plane. A distance is a measure between two points. A line is made up of infinitely many points and has length but no width. A plane is a flat surface made up of infinitely many lines and points and has length and width. So the term described by an ordered pair \((x,y)\) on a coordinate plane is a point.

Answer:

point
