whole number line
The convention is to locate positive numbers to the right of the point identified as zero on a number line.
Point, zero; line, one: length but no width
Indeed no. It is only by convention and for convenience we use zero as the origin. But for example -273 C (absolute zero) could be a starting point in low temperature physics.
It is the point which separates the positive numbers from the negative ones.
whole number line
It is the real number whose length represents the distance from the zero on the line to the point on the line.
It is the number that represents the distance of the point from the origin, or zero. It may be called the coordinate.
A line on a graph with zero slope is a horizontalline.' Y ' is the same number at every point on the line.
this is also called the origin on that line. it is the point equidistant between -1 and +1.
The convention is to locate positive numbers to the right of the point identified as zero on a number line.
Point, zero; line, one: length but no width
The absolute value or the modulus.
Conventionally, it is the point one unit to the left of zero on the number line.
Indeed no. It is only by convention and for convenience we use zero as the origin. But for example -273 C (absolute zero) could be a starting point in low temperature physics.
It is the point which separates the positive numbers from the negative ones.
A mark on the number one unit to the left of the zero point.
