Answer: The slope is -1
Step-by-step explanation:
The slope of the line in Slope-intercept form is:
[tex]y=mx+b[/tex]
Where "m" is the slope of the line and "b" is the y-intercept.
You can observe that the equation of the line [tex]y= -x + 8[/tex] is written in Slope-intercept form. Therefore, you can identify that the slope of the line described by this equation is:
[tex]m=-1[/tex]
And the y-intercept is:
[tex]b=8[/tex]
