What is the slope of a line. its a straight line just below the x-axis (horizontol) and passes through -1 on the y-axis, is the slope -1, or undefined?

Answer 1

slope = 0
(not steep at all :)
the slope of any horizontal line is 0
y = m x + b
if m = 0, y = b forever for any x

Answer 2

K thanks! could you possibly answer my other question below the post of this one?
