Answer: The slope is -1
Step-by-step explanation:
1. By definition, the equation of the line has the following form:
[tex]y=mx+b[/tex]
Where m is the slope and b is the y-intercept.
2. The line given in the problem is [tex]y=-x-4[/tex].
3. Keeping on mind the form of the equation of the line, you can identify that slope and the y-intercept are:
[tex]m=-1[/tex]
[tex]b=-4[/tex]
