The meridian of longitude passing over Greenwich, England.
To rotate a figure 90 degrees clockwise about the origin, simply swap the x and y coordinates of each point and then negate the new y-coordinate. This is equivalent to reflecting the figure over the line y = x and then over the y-axis.
prime meridian
You're talking about the Prime Meridian ... the imaginary line that defines the origin of longitude on Earth.But issue must be taken with your use of the terms "from" and "to". No meridian, including the Prime one, has a defined beginning or end point. They simply join the poles.
At the Greenwich meridian, and the international date line.

A longitude is a line that circles the globe from north to south. Longitudes are used to specify a location in degrees from east to west on the globe. See picture above. If the picture hasn't been changed the lines (not the equator) are longitudinal lines.

the distance from the origin
The lines of latitude provide vertical (north-south) coordinates on a map or globe. Lines of longitude provide horizontal (east-west) coordinates. The defined geographical point is where the latitude line intersects the longitude line.
First, look on the map to find the line of latitude that the coordinates reference. If the exact line of latitude isn't shown on the map, estimate it by looking at the lines that are available. Then look on the map to find the longitude line that the coordinates reference. Once you have found the two lines, follow them both towards the point where they intersect. That is the location the coordinates reference.
The equator is the origin for the lines of latitude
The system of latitude and longitude is used to describe the location of points on the surface of the earth. Celestial objects don't have latitude and longitude. There is a similar system defined in the sky. Those coordinates are called Right Ascension and Declination.
Well, let's see . . . . . A "meridian" is a line of constant longitude, so wherever you are on it, the longitude is always the same number. Also, a meridian of longitude is a line that stretches all the way between the north pole and the south pole, covering all possible latitudes. So the coordinates on the central meridian are: (Any latitude you want), and (The same longitude everywhere on it).

No. The Prime Meridian has several dips and bends.

Coordinates given in WikiPedia indicate a longitude of 21 degrees east. This puts the point at which this coordinate is set east of the 20 degree line.
