Design of a fixed base-voltage BJT amplifier with a temperature stabilizing resistor at BJT's emitter.

Design a fixed base-voltage BJT amplifier having a temperature stabilizing resistor RE 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 specifications.
