The number line shows a closed point at \(-7\) with an arrow extending indefinitely to the left. A closed point indicates that the value \(-7\) is included in the solution set.
Since the arrow goes indefinitely left, it means all numbers less than or equal to \(-7\) are included.
Therefore, the correct inequality represented by the number line is:
x ≤ −7
This corresponds to the option "x less-than-or-equal-to negative 7."
