The International Date Line corresponds closely, but not exactly, to the 180 degree line of longitude.
It's called a Fall Line.
The farthest north latitude is 90° North. It is a single point, called the 'north pole'.
No. A line can lie in many planes. A plane can be defined by three non-linear points. Since a line is defined by only two points, we need another point. (Note that point C alone, or line AB alone belong to an infinite number of planes.)
The line formed by the infinite number of points with zero latitude is commonly called the "equator".
The coordinate of that number.
absolute power
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 number that represents the distance of the point from the origin, or zero. It may be called the coordinate.
