What is this saying? ?

d

step-by-step explanation:

an inequality is an expression which means more than one number is a solution. we graph the solutions on a number line to show all possible values. we graph using circles and arrows.

equal to and less/greater than are graphed with filled in circles on the value.only less/greater than (not equal to) are graphed with open (not filled in) circles on the value.we draw an arrow the direction the solutions satisfy the inequality. generally this is the direction the inequality itself points.

this is a filled in circle on -2 so this is . this means only answers c and d are options.

answer d points to the right.
