If we bias the device at a higher voltage, a higher Vgs, in the absence of a signal, it means we also have a higher current. Perhaps then, the transconductance is higher because this is a nonlinear equation. Right? There's a nonlinear equation, so because of this non-linearity, the slope, due to the second-order effect, the power of two, keeps increasing as we increase the bias voltage. This tells us that a higher bias voltage for the gate-source gives us a higher current and a higher slope.
