#<# or #>#

Explanation:

There are four types of inequality signs:

#<, >, <=, >=#

If the boundary line is dashed then the inequality does not include that line. That means the equation can only be using either of the first two symbols.

#<, >#

On the other hand, a continuous line with no breaks means the inequality does include the boundary line. Likewise, the equation uses one of the last two symbols.

#<=, >=#
