Find Q point in common base BJT configuration

+0
−1

Suppose we have this graph:

How can we find the operating point (Q)?In common emitter collector we just draw a line from the vertical axis (Ic) at the point (0,VCC/RC) to the horizontal axis at the point(VCC,0) and where that line intersects with the IC/VCE curve for some specific IB , there is our operating point but now 1)we have VCB instead of VCE and 2)VCB may take negative values.

Here is the circuit:

Help appreciated!
