Yes. Longitude lines on a map are vertical and latitude lines are horizontal.
But it could be the other way around too. It depends on how you hold your map.
Yes.
There isn't any and that is why the slope of a vertical line is not defined.
run as in slope of a line is zero . horizontal lines have no slope and vertical lines have a slope of zero
In map graphs, a vertical line is typically called a "longitude" line, while a horizontal line is referred to as a "latitude" line. Longitude lines run from the North Pole to the South Pole and measure distances east and west of the Prime Meridian. Latitude lines run parallel to the Equator and measure distances north and south of it. Together, these lines create a grid that helps in pinpointing locations on the Earth's surface.
The equator is not a longitude line. It is a circle that divides the Earth into the Northern and Southern Hemispheres. Longitudes are vertical lines that run from the North Pole to the South Pole on the Earth's surface.
north-south
North-South
A line running north and south/ up and down is called a vertical line.
On a normal map or atlas they are vertical.
North and south.
The prime meridian is the longitude (vertical) line that measures 0 degrees.
When run = 0. That is to say, when the line is vertical.
