Plot signal frequency.

I have a signal with A = 1, F = 3 Hz. I then have a sample rate of 5 Hz. Now I can theoretically calculate this by using fsample -sample and get that my new aliasing frequency would be 2 Hz. What I'm not sure, is how I would plot this on a graph? I've done a graph where you can see that 1s is when the sinwave have repeated itself three times, but how would I plot a frequency of 5hz on my original 3hz frequency?
