Two. Two points determine a line. Three points determine a plane.

how do you identify points of contention
depends on the position of the points if points are collinear, we have just only one line, the minimum number. If points are in different position (if any of the two points are not collinear) we have 21 lines (7C2), the maximum number of lines.
Yes, ordered pairs identify points in a coordinate plane. If that doesn't answer your question, please restate it (say it another way).

The minimum is two points, one point at each end of the line.

A minimum of 6 sets of data are needed to make a valid conclusion.
There can be no minimum number - it is simply not possible. Given any n points in 3-dimensional space, it is possible to find a polynomial that will generate a curve going through each of those points. There are other functions which will also do the trick. So, given any number of points, it would be impossible to determine whether they were generated by a fractal or a polynomial (or other function).

min 3, but more would be better. The max/min point is a must and a couple of points to the left and right of it.
In the United States, the minimum number of matching points required to identify an unknown latent print can vary depending on the agency and specific circumstances. However, a common standard used by many law enforcement agencies is around 8 to 12 points of comparison. Ultimately, the determination of a match also considers the overall quality of the prints and the context of the investigation.
The minimum number of points required to geo-reference an object typically depends on the complexity of the object's shape and the desired accuracy. For a simple object, at least three non-collinear points are necessary to establish a coordinate system in two dimensions. In three dimensions, a minimum of four non-coplanar points is needed to accurately define the object's position. However, more points can improve accuracy and reliability.

In Euclidean geometry each line contains a minimum of an infinite number of points. In projective geometry, though, a line may have as few as two points.
