Answer: The slope is -2
Explanation:
It is important to remember that the equation of the line in Slope-Intercept form is the following:

Where "m" is the slope of the line and "b" is the y-intercept.
In this case you can observe that the given equation of the line
is written in Slope-Intercept form.
Therefore, you can identify that the slope "m" is:

And the y-intercept "b" is:
