Answer

Draw a closed circle on -2 and draw a line to the right Draw a closed circle on -5 and draw a line to the left

Work Step by Step

$t\geq-2$ means that all real numbers for the value of t are greater than or equal to -2. Since t=-2 is a solution, draw a closed circle on -2 and draw a line to the right. $t\leq-5$ means that all real numbers for the value of t are less than or equal to -5. Since t=-5 is a solution, draw a closed circle on -5 and draw a line to the left
