Answer:

open left

Step-by-step explanation:

We can distribute the left side to get [tex]3x-27<-18[/tex].

We can then add [tex]27[/tex] to both sides of the equation to get [tex]3x<9[/tex].

We can finally divide both sides of the equation to get [tex]x<3[/tex].

Because it's a [tex]<[/tex] and not a [tex]<=[/tex], it is closed. And because the inequality opens to the right, it faces to the left.

So, it is a open left graph.
