Answer:
lower left (already identified)
Explanation:
You want the graph showing x < 2.
Line type
The boundary line of the solution area will be x = 2. Because that line is not included in the space x < 2, the line is dashed. (Eliminates graphs on the right.)
Shading
The solution space includes values of x that are less than 2. That means they are to the left of the boundary line. Shading will be left of the dashed line. (Eliminates graphs on the top.)
The correct graph of x < 2 is the one at lower left, already highlighted in the image.
