When interpreting a number line, typically a solid dot represents the inclusion of that value (i.e., it is equal to and satisfies the inequality), while an open dot represents the exclusion of that value (i.e., it is not equal to and does not satisfy the inequality). The colored line represents the region where the inequality holds true.

Based on the provided number line graph, we can see the portion of the number line to the left of  , represented by an arrow pointing to the left with an closed circle on  , indicates that all numbers less than   are solutions to the inequality, including
