# numpy.polynomial.polynomial.polyline

polynomial.polynomial.polyline(off, scl)

  Returns an array representing a linear polynomial.

  Parameters
    off, scl scalars

      The “y-intercept” and “slope” of the line, respectively.

  Returns
    y ndarray

      This module’s representation of the linear polynomial `off + scl*x`.
