15 degrees E (15 degrees east) 30 degrees E (30 degrees east) and so on.
Longitude measures the distance east and west of the prime meridian.
15 degrees W (15 degrees west) 30 degrees W (30 degrees west) and so on.
The prime meridian is located at 0 degrees longitude and passes through Greenwich, England. The international dateline is located at 180 degrees longitude and is opposite the prime meridian, roughly along the 180th meridian in the Pacific Ocean.
That's going to depend on how you're holding your map or globe. -- If the north pole is at the top, then meridians to the left of the Prime Meridian mark west longitudes. -- If the south pole is at the top, then meridians to the left of the Prime one mark east longitudes. -- If the north and south poles are toward the sides of the map, then the Prime Meridian is a horizontal line between them, and there is nothing on Earth to the left or right of it.

The right line on a globe is the Prime Meridian, located at 0° longitude, and the left line is the International Date Line, roughly at 180° longitude. The Prime Meridian represents the starting point for measuring longitude, while the International Date Line marks where the date changes as you travel east or west across it.

You're on the right track, but don't get hung up on 'lines'. Longitude is the angle from the Prime Meridian east or west to the place of interest.
The Prime Meridian
"... the right and left lines of a globe?" I assume the reference is to the lines of longitude? The Prime Meridian is zero longitude which is a line that passed through the Greenwich observatory, London, England. To the left is west. To the right is east.
Longitude is up and down latitude goes left and right . Hope this helped.==============================To put a finer point on it:The answer to that question depends on how you hold your mapor mount your globe.The longitude of any place is the angle east or west between thatplace and the Prime Meridian.
Oh, dude, the prime meridian is just like the zero degrees longitude line that runs through Greenwich, England, right? So, technically, there are infinite cities both east and west of it because the Earth is a big ol' sphere with a whole bunch of cities all over the place. But hey, who's counting, right?
The Equator runs east-west and the prime meridian runs north-south.
That depends on what you mean by "to the right of." If you are facing north, or if you are looking at a map that has north at the top, then the eastern hemisphere is to the right of the Prime Meridian.
