The number line is scalable, meaning it can be any distance you want.
It is the number minus 0
... equal to the number.
The distance is 0.
A number's distance from 0 on a number line is called absolute value. The absolute value of 5 is 5 and the absolute value of -5 is also 5.
the absolute value
Its absolute value.
On a horizontal number line, the distance is 0!
0 and 4
From 0, it is one tenth of the distance from 0 to 1.
Its absolute value or magnitude or modulus.
Its absolute value (or modulus).
Yes; it is a distance on a number line starting at 0 and going positive only.

The additive inverse.
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.
6/10 of the distance from 0 to 1.
+4 and -4 both do.
