<h2>
Answer:</h2>
The undefined geometric term is described as a location on a coordinated plane that designated by an ordered pair,(x,y) is:
Point
<h2>
Step-by-step explanation:</h2>
There are three undefined terms in geometry--
1) Point
2) Line
3) Plane
<u>Point--</u>
A point is just a location on a coordinate grid.
It has no dimension and in represented by (x,y)
<u>Line--</u>
A line is a line of collection of set of points and is extended infinitely in both the directions.
The x-axis may also be considered as a line as it satisfies the equation y=0
The general equation of line in coordinate plane is:
<u>Plane--</u>
A plane is a two dimensional surface which extends infinitely.
Hence, the answer is:
Point
