($-\infty, \frac{7}{2}$]

#### Work Step by Step

$Solve$ $the$ $linear$ $inequality$. $Express$ $the$ $solution$ $using$ $interval$ $notation$ $and$ $graph$ $the$ $solution$ $set$: 2x $\leq$ 7 Solve for x 2x $\leq$ 7 Divide both sides by 2 $\frac{2x}{2}$ $\leq$ $\frac{7}{2}$ $x \leq \frac{7}{2}$ Express the solution in interval notation ($-\infty, \frac{7}{2}$]
