I know the voltage gain for transitor amplifiers is calculated by Vout / Vin
or the gradient of the linear region of a Vout vs. Vin graph but is this
just the magnitude? OR does it have a negative value if it is an inverting
amplifier?

Thanks

** Basically - gain is purely magnitude.

But hey - some like it both ways !!!

Amplifier X has a gain of -100.

Amplifier X is an inverting amplifier with a gain of 100.

Both are correct.
