Think of the difference between a line and a line segment. A line segment is defined by {2x+1 ; 0<x<5} while a line is simply defined {2x+1 ; x>0} these mathematical expressions are accurate definitions of what a finite segment is, and an line toward positive infinity, and can be negative infinity as well if it is defined {2x+1 : x<0}.
I can't think any other way to express infinity, it seems to be just a function where every input has a possible output.
In terms of space time, infinity would hold true that every point in the space time continuum has an equal number of points in an infinite series. Bear in mind infinity is interesting, but defined in theoretical terms.

x/0
Technically that is an undefined result which has no real number solution.
