I have some problems about load line of this circuit...

Usually, to find load line i calculate current in transitor when
transistor is shorted and when is open circuit. In this case, when
transtistor is shorted, vout=vss and current in transistor M1 shoud be
Iq+(Vout/Rl): is this right? How can i obtain (Vdd-Vss)/Rl?
Thanks in advance

What you actually need is two load poly-lines. Cutoff in one part
will actually occupy much but a minority of the active load line in
the other part.
