#x+1=0# is the equation of a vertical line.

Explanation:

There is no definition of the slope of a vertical line.

The line has #x# intercept #-1#. It does not have a #y# intercept.

It can be written #x=-1#, but it cannot by written in slope intercept form (#y=mx+b#) because it does not have a slope and it does not have a #y# intercept.
