I'm not aware of any such equation. The equation you want is of the form x(t) = .

No.
The first step is to figure out the amplitude. Can you think how to read that off the graph?
 
I just saw the wavelength and assumed it was 5.

This equation is wrong.

Amplitude is not wavelength. What do you think is meant by the amplitude of a wave?
You still haven't provided any correct equations related to SHM. Don't you have any notes or textbooks? If not, read it up online.
