Number line with open circle on 9 and shading to the left. Which of the following inequalities best represents the graph above? x < 9 x > 9 x ≤ 9 x ≥ 9
X is less than 9. We know it is only less than and not equal to because the dot is open. Just as well, because the line is shaded to the left of this point, we know x's value is decreasing; thus making it less than 9.
