Plot the output characteristics and use it to determine the output resitance, construct the load line for the transistor when the collector supply voltage is 18v and load resistance is 600Ω, identify the quiescent point on the graph and give the values of the quiescent current and voltage. develop a table from the transistor output characteristic curve for when Vce=10V and hence plot the transfer characteristic of this transistor. Evaluate also the gain of the transistor.

please i need a guide to what i should do to solve this problem.
thanks you
