It is the prime meridian.
Longitude is the angular distance measured in degrees east or west of the Prime Meridian, which runs through Greenwich, England. It helps pinpoint a specific location on Earth's surface by providing a reference point for measuring east-west position.
North - South or South - North depending where you are at time
The axis,most probably, I have a Social Studies HW to do,and this question is hard
There is no begining or end. It is a line that goes on forever passing thru the north and south poles.
The IDL should nominally follow the meridian of longitude that is 180 degrees from the Greenwich Prime Meridian ... roughly down the middle of the Pacific Ocean. But in defining the line, it was zigged and zagged where necessary to avoid cutting across nations and politically contiguous island groups.
Longitude is measured up & down from the Prime Greenwich Meridian (Greenwich).
Its a datum, 0 deg. longitude, line from north pole to south pole which passes through greenwich england (known as the greenwich (or prime) meridian), positions of all other longitudes are relative to this line, longitude 30 degrees east for example, looking down on the north pole, copy and rotate greenwich meridian 30 degrees anticlockwise, this is longitude east 30 degrees, if you include a latitude also , this gives you a position on earths surface.

zero degrees, runs through Greenwich and Waltham Abbey
Multiple cities are located on the prime meridian. It starts at the North Pole and goes down in a straight line to the South Pole. The city most commonly associated with the Prime Meridian is Greenwich, England. It's home to the Royal Observatory. Other cities that are on the Prime Meridian include Peachaven at the south of England, Villers-sur-Mer in Franch, Castellon de la Plana in Spain, Stidia in Alergia and goes through Mali, Burkina Faso, Togo, Ghana, and Antarctica.

I believe longitude goes up and down
Every meridian of constant longitude joins the north pole to the south pole.
The IDL should nominally follow the meridian of longitude that is 180 degrees from the Greenwich Prime Meridian ... roughly down the middle of the Pacific Ocean. But in defining the line, it was zigged and zagged where necessary to avoid cutting across nations and politically contiguous island groups.
On a globe, draw the shortest line you possibly can between the north pole and south pole, and make sure it passes through Greenwich, a suburb of London in England. You can make sure it's the shortest possible line by stretching a rubber band between the north and south poles of the globe. The rubber band will just naturally keep pulling itself shorter and shorter until it can't get any shorter.
