$t\leq8$
$8t\leq64\longrightarrow$ divide both sides by 8 $8t\div8\leq64\div8\longrightarrow$ divide $t\leq8$ Check the endpoint. Substitute 8 for t. $8(8)\overset?=64$ $8=8\checkmark$ Check the inequality. Choose any number less than 8 and substitute for t. $8(7)\overset?\leq64$ $56\leq64\checkmark$ Since 8 is included in the solution, the endpoint of the graph is a solid circle.
