We can rewrite as

$y = sin x cos π - cos x sin (π) - 1$ $y = sinxcospi - cosxsin(pi) - 1$

$y = - sin x - 1$ $y = -sinx - 1$

This is the basic sine graph reflected in the x-axis and transformed 1 unit down.

Here is the graph:

The amplitude is $1$ $1$ , the phase shift is $0$ $0$ and the period is $2 π$ $2pi$ .

Hopefully this helps!
