Answer:

The graph in the attached figure

Step-by-step explanation:

we have

[tex]3x < -9[/tex]

solve for x

Divide by [tex]3[/tex] both sides

[tex]3x/3 < -9/3[/tex]

[tex]x < -3[/tex]

The solution is the interval------>[tex](-infinite, -3)[/tex] -

All real numbers less than [tex]-3[/tex]

In a number line the solution is the shaded area to the left of the dashed line (open circle)
