Setting break points when doing any kind of programming lets you pause the processing, so that you can spot-check your variables and make sure that they are what you expect them to be.
what is the technical name for debugging?
what is The set of all points collinear to two points?
No, but is an infinite set of points.
Debugging
Profiling is about executing a program and finding out how much time it spends in each routine. The goal of profiling is often finding slow routines in a program and optimizing them. Profiling is done on working code. Debugging is about finding code that is not working, i.e. has some kind of defect. The program is known to have a defect because some set of inputs causes a set of outputs that are known to be wrong. Debugging is the process of finding the source of the defect in the code and fixing that location and any other downstream locations so that the set of inputs is correctly rendered into the set of outputs.
Debugging in Google Chrome can be done using Inspect Element. F12 is the shortcut key for enabling debugging.
A set of points on a straight line are called 'collinear points'.
a set of points on a flat surface?
The solution set is the set of all points representing solutions.

Collinear set of points
An infinite set can not terminate.
