Answer:
The slope of line y=-8 is 0, and any line that lies parallel to it will also be 0. This is because if an equation does not have an x-value, the line will be straight and horizontal, making it's slope 0.
Answer:
The function [tex]y=-8[/tex] It is a horizontal line, in this function for any value of x, the value in y is -8.
The slope for horizontal lines is 0.
If we have a line parallel to this one, it will also be a horizontal line, so its slope will be 0.
A perpendicular line will be a vertical line in the plane.
Vertical lines have an indefinite slope, or in some cases they are called an infinite slope, they have no defined value.
