In Example 4(b), change ≤ to > and then graph the resulting inequality.

Data from Example 4(b)

To graph x ≤ 1, we follow the same basic procedure as in part (a), except that we use a solid circle and the arrowhead points to the left. See Fig. 17.1(b). The solid circle shows that the point is part of the indicated solution.
