A line in the euclidean sense is defined as the shortest distance between two points. It is defined to be in 1 direction only, i.e. infiinitly thin but also infinitly long. In the cartesian coordinate system it is usually described as an equation in x and y of the form 
where m is the slope of the line and b is the y-intercept. Any two points define a line, and given specific 
one can solve for the line's equation.
