A line is a one-dimensional object that exists in one dimension or higher. A line has infinite length, zero width, and zero height. Two (or more) points define a line. The following equation gives a non-vertical line in two-dimensions where *m* is the slope (gradient) of the line, *b* is the *y*-intercept of the line, and *x* is the independent variable of the function *y* = *f*(*x*).

y=mx+b

In two dimensions, the following equation describes every line ** L** (including vertical lines), where

ax+by=c, whereaandbare not both zero

In three dimensions, a line is given by the following two linear equations, where (*a _{1}*,
