Drawing Horizontal Lines in LaTeX

Drawing Horizontal Lines in LaTeX

Lines can be drawin in LaTeX using the \line function. This takes an x-slope, y-slope and length like so:
\line(x-slope,y-slope){length}
To draw a horizontal line (or horizontal rule), set the x-slope to 1 and the y-slope to zero.
Depending on the margins which have been set, a length of 450 will draw a line which is the width of the page (minus the margins).
If you’re looking for a clean line to divide the page, try the following:
\begin{center}
\line(1,0){250}
\end{center}
