collinear
A point on a line divides the line into two halves. All the points of the line that lie on one side of this point form a half-line or ray. This half-line extends infinitely in one direction from the chosen point, including all the points on that side of the line. Thus, it represents all the points that are either to the left or right of the specified point, depending on the chosen orientation.
This describes a ray.
Yes, it is true that through any three points, if they are not collinear (not all lying on the same straight line), there exists exactly one line that can be drawn through any two of those points. However, if the three points are collinear, they all lie on the same line, meaning that there is still only one line that can be associated with them. In summary, the statement holds true under the condition that the points are not all collinear.
Because the "best fit" line is usually required to be a straight line, but the data points are not all on one straight line. (If they were, then the best-fit line would be a real no-brainer.)
A line can be tangent to a circle in which case it intersects it in one point, it can intersect it in two points, or no points at all. So the choices are 0,1 or 2.

A half line? A ray?
This describes a ray.
Noncollinear points are points which are not all on a common line.
if there are three or more points not all of which lie on the same line then they are known as non linear pointsif there are specifically three points not all of which lie on the same line then they are known as coplanar points as they will always lie on one plane
Because the "best fit" line is usually required to be a straight line, but the data points are not all on one straight line. (If they were, then the best-fit line would be a real no-brainer.)
All points on the same line are colinear but if you mean what are the points all called collectively - they represent a "locus of points".
'Line Segment' is a portion of a line that includes two points and all of the collinear points between the hypothetical two points also 'Line Segment' because a line or line segment is a set of infinite points and the infinite points are collinear....
