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=[c1,c2,c3], it constructs a line whose equation is c1x+c2y+c3=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.
