First, you draw a number line. You then make points for the counting numbers, and place the mixed numbers and decimals between these points, getting their own points and labels.
non collinear point or points? no collinear points are points not on the same line. keep in mind that you have to have at least 3 points to make that happen.
no, they make a line segment.
One point cannot make a line or even a piece of a line. You need at least two points (in projective geometry) and infinitely many in classic geometry.
no just jocking

any points along the line described by the equation x=anything will give you a vertical line on a graph
A line segment in geometry is a distinctive line that has end points.
If you plot data points on a graph the rarely will form a straight line. Least squares is a method of finding a line 'close' to all the data points instead of just guessing and drawing a line that looks good. If you have a line, then there is an algebraic formula to find the distance from each point to that line. Then using statistics, you can make the statistically averaged distance from each data point as close as possible to a line. The distances are squared, averaged, and the average of those squared distances may be used to find the regression line.
At least 3
One line only. This is because by definition a line only needs two points. Three points not in a line would make a plane when connected. Two points, when connected, form a line in which there is only one way to pass through points a and b.
No, A plane can be drawn through any 3 points. If the 3 points are collinear then they make a line and a plane can contain a line. If the points are noncollinear then they can be used to form the corners of a triangle; all points of a triangle are in the same plane.
