Given two points $A$ and $B$, it constructs a line passing through such points. You can also extract the corresponding coefficients through the slope() and intersect() commands.

Given a point $A$ and a vector $v$, it constructs a line passing through $A$ with direction vector $v$.

Given a point $A$ and a real $m$, it constructs a line passing through $A$ with slope $m$.

Given a vector $c=\lbrack c_1,c_2,c_3\rbrack$, it constructs a line whose equation is $c_1x+c_2y+c_3=0$.

Given an equation or equations, it constructs a line whose equation(s) are the ones we have provided.

Given two reals $a$ and $b$ (or one real and one infinity), it constructs the line that intersect with x-axis at $x=a$ and with y-axis at $y=b$.

Given a segment, it constructs a line that contains it.

Given a triangle and an integer $n$, it constructs the line that contains the $n$-th edge.

Given a polygon or polygon and an integer $n$, it constructs the line that contains the $n$-th edge.
