    You have your graph of V1 and V2 as functions of Vin. Just plug in the numbers for the resistors and point out that the graph matches the calculation (mention a couple of the points on the graph).

    I have LT Spice, which may be different, but if you look in the "edit simulation command" window there might be a "DC sweep" option.

    In this you can name a voltage source and choose the range of voltages you want it to sweep over.

    If you have this, feed in your circuit and do a simulation and you will get a graph when you click on the points required. You can then grab this by doing a screen grab or using your Cadence program.
