    Best answer as selected by question asker.

    The vectorial equation of the line "d" is:

    x = xA + t*xu

    y = yA + t*yu

    z = zA + t*zu

    By substituting everything we know from the enunciation:

    x = 2 + t*1

    y = -4 + t*1

    z = 1 + t*1

    These 3 expressions above represent the parametric form of the equation requested.
