#### Answer

$(-\infty, -\frac{1}{2}]$
Refer to the image below for the graph.

#### Work Step by Step

Add $9x$ on both sides to obtain:
$5+6x \le 2$
Subtract $5$ on both sides to obtain:
$6x \le -3$
Divide by $6$ on both sides to obtain:
$x \le \dfrac{-3}{6}
\\x \le -\dfrac{1}{2}$
The solution set is the set of real numbers less than or equal to $-\dfrac{1}{2}$.
In interval notation, the solution set is:
$(-\infty, -\frac{1}{2}]$
To graph this inequality, plot a solid dot at $x=-\dfrac{1}{2}$ then shade the region to its left.
