$\text{Set Builder Notation: } \{x|x\le2\} \\\text{Interval Notation: } (-\infty,2]$
The given graph shows all the numbers that are less than or equal to $2.$ Hence, the given graph of inequality can be described in the following formats: \begin{array}{l}\require{cancel} \text{Set Builder Notation: } \{x|x\le2\} \\\text{Interval Notation: } (-\infty,2] .\end{array}
