whole number line
It is a perpendicular line that forms a right angle at the point of intersection.
A point on a number line.

At the number 2, draw a vertical line (perpendicular to the number line) and mark a distance of 1 unit on this line. Call this point X The distance from 0 to X is sqrt(5). Put a compass with its point at 0 and the pencil at X, and then draw an arc to cut the number line. That will be sqrt(5) on the number line.
Do you mean a number line?The question you asked contains the answer. Every point on a number line corresponds to a number, and every number has a corresponding point on the number line.
It is the real number whose length represents the distance from the zero on the line to the point on the line.
Any real number can correspond to a point on a line.
At the point 1, draw a perpendicular to the number line. Mark of a length of 1 unit on this line: call that point A.From the 0 on the number line, using a pair of compasses, measure the arc OA and use that length to mark the number line at sqrt(2).Rationale:You have a right angled triangle, with its right angle at the point 1. The base is 1 unit and the vertical height is 1 unit. So, by Pythagoras, the line from 0 to A is sqrt(2) units.At the point 1, draw a perpendicular to the number line.

A line with a point at both ends is called a Segment.
It is a perpendicular line that forms a right angle at the point of intersection.
It's a number line!!
It is the starting point for the number line, also called the origin. Measurements, along the number line, for all other values, are taken from that point.
