Sketch a line in NetLogo From it's coefficents

问题

How can a draw a line in NetLogo given in the following form:

                                    Ax+By+C=0

That is, A , B and C are given.

CODE:

    to make-line[a]; a is list containing A, B and C and in that order.
    let x 0
    let y((-item 2 A) / item 1 A)
    let y1 0
    let x1((-item 2 A) / item 0 A)
    crt 1[
      set size 0.5 setxy x y
      pen-down
      facexy x1 y1
      while [distancexy x1 y1 > 0.5]
          [
           fd 0.1
          ]
         ]
     end

PROBLEM: The points tend to be outside the NetLogo boundaries many a lines.

Given the coefficients of a line, is there a way to draw one using any extensions or library functions directly
