To graph the inequality \( x > 11 \), you would use an open point at 11 to indicate that 11 is not included in the solution set. An arrow extending indefinitely to the right represents all numbers greater than 11.
Therefore, the correct representation is:
A number line ranges from 5 to 15 in increments of 1. An open point is plotted at 11. An arrow extends indefinitely right from the open point past 15 along the number line.
