a
The inequality tells us that all values of are greater than or equal to Thus, is in the solution set and should be marked as a closed circle on the number line.

Since greater values lie to the right on the number line, this part should be marked.

b
The inequality tells us that is greater than all values of This means that is not a solution to the inequality and should be marked as an open circle.

Now, all -values less than lie to the left of Therefore, let us mark this region.

c
The inequality describes all values of that are to the right of on a number line. Note that is not a solution, so we mark this as an open circle on the number line at
d
The inequality describes all the values of that are to the left of on a number line. Note that is a solution, so we mark this as a closed circle at
