The correct graph is the one where the shaded area is below the line y = -2.
The correct graph that represents the inequality y ≤ -2 is the one where the shaded area is below the line y = -2. 
This is because the inequality y ≤ -2 represents all the y-values that are less than or equal to -2. 
Therefore, the correct graph is the one where the shaded area is below the line y = -2.
