reference point
For Latitude, the Equator is the zero point. For Longitude, the Prime Meridian at Greenwich UK, is the starting point of zero.
It is called the epicenter which is the starting point.
the prime meridian is the starting point when measuring the longitude
The starting point would be the equator. Lines of latitude run parallel to the equator.

It would depend on what you were measuring as to how it would be graphed (distance from starting point vs time, distance to a certain point vs time, horizontal location vs vertical location, etc).
Line Segment
The starting point in a race is called the starting line. The end point of a race is called the finish line.
