The only inequality that matches the graph is Ox ≤ 5.
The graph is shaded above the horizontal line y = 5, which means that for all points in the shaded region, y is greater than or equal to 5.
Here is a breakdown of the other answer choices:
x ≤ 5: This inequality describes the region to the left of the vertical line x = 5. The graph is shaded in a region to the right of the line x = 5, so this inequality does not match the graph.
x ≥ 5: This inequality describes the region to the right of the vertical line x = 5. The graph is shaded in a region to the left of the line x = 5, so this inequality does not match the graph.
y ≤ 5: This inequality describes the region below the horizontal line y = 5. The graph is shaded in a region above the line y = 5, so this inequality does not match the graph.
y > 5: This inequality describes the region above the horizontal line y = 5, but it does not include the line itself. The graph is shaded in a region above the line y = 5 and includes the line, so this inequality does not match the graph.
Therefore, the only inequality that matches the graph is x ≤ 5.
