Final answer:
The inequality that shows the relationship between the plotted points on the number line is x ≤ 3.
Step-by-step explanation:
The inequality that shows the relationship between the plotted points on the number line is x ≤ 3. This inequality represents all the points on the number line that are less than or equal to 3.
The plot on the left shows a line from (0,2) to (3,8) while the plot on the right shows a line from (0,3) to (3,3). Since the y-coordinates of the points on the left plot are greater than the corresponding points on the right plot, the inequality should include the less than or equal to symbol.
Therefore, the correct inequality is x ≤ 3.
