Answer:
x ≤ 2
Explanation:
If we say the number line represents values of the variable x, then there is a solid dot at the value x=2. That means x = 2 is included in the inequality being represented.
The solid black arrow extends to the left of x = 2, including all values that are less than 2. Thus that arrow represents all values less than or equal to 2. The inequality is written ...
... x ≤ 2
