Answer
$(-\infty, 2]$
Refer to the graph below.
Work Step by Step
Recall:
The intersection of sets $A$ and $B$, denoted by $A \cap B$, is the set that contains all the elements that are common to both $A$ and $B$.
The graph shows that the numbers common to the two sets are the numbers that are less than or equal to $2$.
Thus, the intersection is $(-\infty, 2]$.
Graph this set by plotting a solid dot at $2$, then shade the region to its left. Refer to the graph above.
