Solution Set: $\emptyset$ (No graph)
$x\le3$ includes the numbers that are less than or equal to $3$. $x\ge6$ includes the numbers that are greater than or equal to $6$. The conjunction "and" means intersection so find the numbers that are common to both inequalities. Note that the two sets have no common elements. Thus, the solution set is $\emptyset$.
