No.Its not necessary.
Inclination can either be negative or positive depending on line's inclination wrt the x-axis.

But isn't inclination in degrees?
ur right.Still inclination can be negative.
If the line is below the x-axis,lets say 30 degree below,the inclination is either -30 degree or +330 degree
Oh ok thank you
