Answer
The dashed line is incorrect.
Work Step by Step
To graph an inequality, first pretend like the equation given has an equal sign instead of an inequality symbol. Then, graph the line. Next, shade the region of the graph containing points that result in true statements when plugged into the inequality. Finally, if the inequality is strictly less than or greater than (rather than having an equal sign under it), then dash the line drawn.
Since the graph is greater than or equal to, the line should not be dashed.
