    Re: graph transformation

    at the $y$ axis $\theta = 0$

    $\tan(0-45^\circ) = \tan(-45^\circ) = -1$

    Re: graph transformation

    Your two axes are the $y$-axis and the $\theta$-axis. If you want to know when the graph meets one axis, set the variable for the other axis to zero. This gives $y = \tan (-45^\circ ) = -1$.
    Thanks from AbYz
