    Ah ah I thought it might have been that, but I don't know how to find the line made by arg(z)? Am I just being really stupid and this is actually really easy

    Say

    z = a+bi



arg(z) = \tan \theta

    Where

     \tan \theta = \frac{b}{a}

    Extend this line segment you get into a line and you get:

     arg(z)
