Subscript Notation for Coordinate Points
When working with two or more points on a coordinate plane, the same generic symbol cannot represent different points without a way to tell them apart. Mathematicians use subscripts — small numbers written slightly below and to the right of a variable — to label each point uniquely:
- The first point is written , read " sub 1, sub 1."
- The second point is written , read " sub 2, sub 2."
If more than two points are involved, the pattern continues with , , and so on. Subscripts work much like last-name initials used to tell apart classmates who share a first name — they add just enough detail to make each label unique without changing the underlying idea of an ordered pair.

Subscript Notation for Coordinate Points
A logistics company uses a rectangular coordinate system to track the location of delivery vehicles on a map. If a vehicle is located at the ordered pair (15, 8), what is the mathematical term for the first number, 15, which indicates the vehicle's horizontal position?
A warehouse manager uses a coordinate grid to map the location of storage bins. Match each term related to the bin location (15, 22) with its correct mathematical description.
In a digital mapping system used for fleet management, the term 'ordered' in an 'ordered pair' implies that reversing the sequence of the two numbers will generally identify a different location on the map.
Digital Layout and Coordinate Systems
A logistics coordinator is mapping delivery zones on a coordinate grid. A specific zone is centered at the point (15, 22). In this ordered pair, the number 22, which indicates the vertical position on the map, is called the ________.
