The equator is the line made up of every point on Earth at zero latitude.
equator
its called the 38th paralell
The 38th parallel
The equator is the 'zero' of latitude, so the smaller the latitude number is, the closer it is to the equator. There's no such thing as the 'smallest'. You can name any latitude you want, and no matter how small it is, I can always name a smaller one.

The northern line of latitude closest to Jamestown, Virginia, is approximately 37 degrees North. This latitude runs through several locations in the United States, including parts of Virginia. Jamestown itself is situated just slightly south of this line, at about 37.2 degrees North.
There's no such thing as "the closest line". There's no standard set of "lines" that everybody must use. You can draw a line on your map at ANY latitude. The main door of the terminal building at Billy Bishop Toronto City Airport is located at 43.6316° north latitude 79.3959° west longitude. There are an infinite number of other points in Toronto, and most of them are located at different latitudes.
About 23.5 degrees
The closest line of latitude to Mexico City is the Tropic of Cancer, at 30 degrees north. Mexico City itself is close to 19° N.
The Tropic of Cancer.
The latitude of the obelisk in the center of St. Peter's Square in the Vatican is 41° 54' 08.05" north. The latitude of the center of the Arch of Constantine, near the Colosseum, is 41° 53' 21.85" north. You wouldn't ask "What mark on the ruler is closest to your height ?" You would ask "How tall are you ?"
The equator is the 'zero' of latitude, so the smaller the latitude number is, the closer it is to the equator. There's no such thing as the 'closest' or smallest. You can name any latitude you want to, and no matter how small it is, I can always name a smaller one.
The center of Mexico City is located at 19.42° north latitude 99.13° west longitude. Would you ask someone "What line on the ruler is closest to your height ?" I'm guessing you'd ask him "How tall are you ?" Forget about "lines". There is no standard set of of latitude and longitude lines from which you have to choose one that's somewhere close.
The question seems incomplete, as it doesn't specify what "w" refers to. However, if you meant to ask about a specific location or phenomenon, please clarify, and I'd be happy to provide the closest line of latitude. Generally, lines of latitude, such as the Equator (0°), Tropic of Cancer (23.5° N), and Tropic of Capricorn (23.5° S), mark significant points on the Earth's surface.
The equator is an imaginary line that circles the earth at 0 degrees latitude. Many things lie along that line. The equator is the 'zero' of latitude, so the smaller the latitude number is, the closer it is to the equator. There's no such thing as the 'smallest'. You can name any latitude you want, and no matter how small it is, I can always name a smaller one.
a latitude line is a line going from east to west. Just like the equator. the equator is a latitude line measuring at ) degrees latitude.
