Design of a fixed-bias BJT amplifier with a temperature stabilizing resistor at BJT's emitter and a negative power supply.

Design a fixed-bias BJT amplifier having a temperature stabilizing resistor RE and a negative power supply so that its operating point is as shown in the IV graph. If only [commercially availble resistors] were used, how much would the Q-point deviate from the desired specification.
