Combining Line plots

In Mathematica, is it possible to draw 2 or more line plots on the same graph and if so, how is it done?

Give a list of function to be plotted. For example:

Plot[{Sin[x], Cos[x]}, {x, 0, 2 \[Pi]}]

Here are two that I want to plot on the same set of axes.

#1:

PopValue = {273.8, 126.8, 178.1, 201.9, 151.4, 159.0, 183.5, 126.5,
145.2, 85.0, 164.3, 328.1, 155.7, 127.4, 194.2, 161.2, 129.0,
112.8, 137.9, 147.0, 113.2, 157.5, 135.7, 134.2};

ListPlot[PopValue, Joined → True, AxesLabel → {“Year”, “Birds”},
AxesOrigin → {0, 0}]

#2:

nMax = 23;
p0 = 273.8;

pOneSim = Table[0, {n, 0, nMax}];
pOneSim[[1]] = p0;

Do[pOneSim[[n]] =
RandomReal[NormalDistribution[0.59, 0.12]]*pOneSim[[n - 1]] +
RandomReal[NormalDistribution[63.6, 52.4]], {n, 2, nMax + 1}];

pPoints = Table[{n - 1, pOneSim[[n]]}, {n, 1, nMax + 1}];

ListPlot[pPoints, Joined → True, AxesLabel → {“Years”, “Birds”}]

Thank you.

You can combine your two plots by assigning them to variables, p1 and p2 and then using Show[p1,p2]

OK, I will try that. Thanks for the help.
