Question 6007
The line y = 8 is a horizontal line, and the slope of ANY horizontal line is 0.  Any line parallel to a horizontal line is going in the same direction, so it has the same slope, ZERO.


Any line perpendicular to any horizontal line must be a vertical line, and the slope of a vertical line is undefined.  So the slope of any line perpendicular to y = 8 is UNDEFINED.
