For a function to be parallel to another, the slopes MUST be the same, and y-intercept must be different; in this case, the slope is -x and the y-intercept is -4. 
Since the slope has to be equal to the original function, and we're given the point (-3,1) we may:$$y=-x+b \rightarrow 1=-(-3)+b \rightarrow 1=3+b$$$$-2=b$$
Plug that in now into y=mx+b. 
y=-x-2
b
