#### Answer

Solution Set:
$[-3, \infty)$
Refer to the image below for the graph.

#### Work Step by Step

Subtract 3 on both sides of the inequality to obtain:
$y \ge 0-3
\\y \ge -3$
On a number line, the numbers that are greater than or equal to $-3$ are found from $-3$ to the right.
Thus, to graph the solution set on a number line, plot a solid dot at $y=-3$ and shade the region to its right. (refer to the attached image in the answer part above)
