Two. Two points determine a line. Three points determine a plane.
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.
Contour lines connect points of equal elevation while isobars connect points of equal pressure

3.Any three points will determine a plane, provided they are not collinear. If you pick any two points, you can draw a line to connect them.

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.
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.
15 points is the minimum points
