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 right of , represented by an arrow
pointing to the right with a closed circle on , indicates that all
numbers greater than are solutions to the inequality,
including
