Answer 2

A line is defined by two points.

Answer 3

two points in space defines a line

Answer 4

The distance between two points is a line. It is the shortest connection between two points.

A line, or straight line, can be described as an (infinitely) thin, (infinitely) long, perfectly straight curve (the term curve in mathematics includes "straight curves"). In Euclidean geometry, exactly one line can be found that passes through any two points. The line provides the shortest connection between the points.

In two dimensions, two different lines can either be parallel, meaning they never meet, or may intersect at one and only one point. In three or more dimensions, lines may also be skew, meaning they don't meet, but also don't define a plane. Two planes intersect in at most one line. Three or more points that lie on the same line are called collinear.

Answer 5

Ok, here is a good answer, after a bunch of people trying to get free posts.

A line is a one dimensional non terminating continuation of points. It can only goes in exactly opposite direction. If it went in any other directions, then it would be 2 dimensional and wouldn't be a line anymore

Answer 6

A line is a breadthless length that lies evenly with the points itself. The extremities of a line are points.

Answer 7

They say a line is an infinite array of infinitely small points, which [and I am quoting this from someone whose name I cannot recall] is impossible, because infinitely small points cannot sum up to any size, and if the points are not infinitely small, there cannot be an infinite amount of them.

There is, apparently, no such thing.

Either the shortest distance between two points. Or something ridiculous a stranger says to you in a bar hoping to seduce you! Ha ha....
