#### Answer

$m\geq2$

#### Work Step by Step

$3m\geq6\longrightarrow$ divide both sides by 3
$3m\div3\geq6\div3\longrightarrow$ divide
$m\geq 2$
Check the endpoint.
$3(2)\overset?=6$
$6=6\checkmark$
Check the inequality.
$3(3)\overset?\geq6$
$9\geq6\checkmark$
Since 2 is included in the solution, the endpoint of the graph is a solid circle.
