The x-coordinate must be the same for all points on the line.
A segment has two end points. If a line has one end point, then it must be called ray.
Goal line.
There must be 67 marbles.
With some slack in the line
Any part of the ball must cross the goal line. Once any part of the ball has "broken the plane" it is a touchdown. The "whole" ball does not need to cross the line. If the ball is touching the white line, but no part of it passes the white line it is NOT a touchdown.
When any part of the ball or any part of the ball carrier touches the out of bounds line, the ball is out of play.
Yes you can throw as many passes as you want as long as you or the ball has not crossed the line of scrimmage, but once you or the ball has crossed that line, you may not forward lateral the ball to another player, the pass must be a backward lateral.
A touchdown is when you have crossed the plane of the end zone either by running the ball into it (which you only need to make sure the ball passes the plane), by knocking over the orange post in the corner of the end zone while in possession of the ball (which are in the end zone), or by catching the ball in the end zone (both feet must be in the end zone when caught).
yes and the ortheroneis downfall
No, the ball must completely cross the goal line before a goal is awarded.
No, road distances are longer then as the crow flies distance. Mountains and lakes must be driven around and rivers must be bridged or crossed by ferry and those structures are rarely available in a straight line.
This is not a goal, the only thing that matters is the ball. For a goal to be scored the whole ball must have crossed the line.
The line of scrimmage is an imaginary line passing through the foremost point of the ball after the ball is marked ready for play. The space occupied by the ball is considered the neutral zone. The defense must stay on their side of the neutral zone and only the snappers hands may be in the neutral zone for the offense. Measurements are taken at the foremost point of the ball and the foremost point must touch the goal line for a touchdown.. When an offense is running out of its own endzone it must get the ball completely out of the endzone or it is a safety.
This line is called the ten foot line.

According to referee Ed Hochuli who is quoted in the article that you can read at the 'Touchdown or No Touchdown' link below, a player who crosses out of bounds is awarded a touchdown if a part of his body touches in the end zone, or the pylon, after the ball crosses the 'imaginary' goal line outside the pylons. I interpret the question to ask if a player lands completely out of bounds but the ball crosses the 'imaginary' goal line outside the pylon, is it a touchdown? The way I understand what I read, the answer is no since no part of the player touched inbounds. Click on the 'Touchdown or No Touchdown' link to read the article and weigh in with your opinions. If I'm understanding your question right, you're asking about the hypothetical goal line that "travels around the world" indefinitely out of bounds. The NFL just changed this rule for the 2008 season, so that the extended goal line no longer exists. The player must now break the plane of the goal line within the field of play, or press the ball against the corner pylon, for the touchdown to count.
