out of bounds
The goal line in football is located at the end of the field, marking the boundary of the end zone where a team scores a touchdown.

You are probably mixing units. If you are talking about playing area it is 100 yards by 53.3 yards for the playing area, not including endzones. See below from Wikipedia.Football is played on a field 360 by 160 feet (120.0 by 53.3 yards; 109.7 by 48.8 meters).[10] The longer boundary lines are sidelines, while the shorter boundary lines are end lines. Sidelines and end lines are out of bounds. Near each end of the field is a goal line; they are 100 yards (91.4 m) apart. A scoring area called an end zone extends 10 yards (9.1 m) beyond each goal line to each end line. The end zone includes the goal line but not the end line.[10] While the playing field is effectively flat, it is common for a field to be built with a slight crown-with the middle of the field higher than the sides-to allow water to drain from the field.
The boundary lines at the ends of the field are "goal lines" or "end lines". The long boundary lines at the sides of the field are "touch lines" or "side lines". In FIFA Laws of the Game, Law 1 describes the field of play in more detail.
In general they are called the beginning and the end. In a race they are called the starting line and the finish line. In real estate they are both called the property line. In geography they are both called the town line, the city line, the county line, the state line.
The end of the railway line is called the terminus. It can also be called the terminal. It is the place where the line ends or terminates.
There are a number of lines on a soccer field. None of them are called boundary lines. The touch lines run up and down the length. They form the sides. The goal lines are across the ends of the field. The touch lines and goal lines define the field's perimeter or its boundary. And a ball that is in play must wholely cross one of these lines (either on the ground or in the air) to be considered out of play.
in engineering drawing, a line with an arrow at each end is called a dimension line
If it has defined end points then it is a line segment.

No. A fotball field is an area of grass or other surface painted in the outline of a football field. A line segment is a straight line which has a defined beginning and end, and is continuous between those points.
A line with two end points is called a line segment:)
