What is the slope of the line described by the equation below?

y= -x + 8

The slope is -1

Step-by-step explanation:

The slope of the line in Slope-intercept form is:

Where "m" is the slope of the line and "b" is the y-intercept.

You can observe that the equation of the line is written in Slope-intercept form. Therefore, you can identify that the slope of the line described by this equation is:

And the y-intercept is:

what i would say the best answer is a. 40.5
