Final answer:
The equation of the line with slope 0 and passing through (8, -1) is y = -1.
Step-by-step explanation:
The equation of a line with a slope of 0 and passing through point (8, -1) can be written in the form y = b, where b is the y-coordinate of the point. In this case, since the point (8, -1) lies on the line, the equation is y = -1.
