To graph an inequality on a number line, we need to make note of two things: the direction of the inequality and whether it is non-strict.
t ≥ 6
Observing the given inequality, we see that all values of t are less than or equal to 6. This means that the solution set lies to the left of 6 on a number line. Furthermore, the inequality symbol indicates that t=6 is a solution, which we will mark with a filled circle on the number line at 6.
