Answer: x < -0.4 (choice C)
Step-by-step explanation
Count the spaces from -1 to 0. There are 5 spaces.
This would mean each tickmark represents 1/5 of a unit.
1/5 = 0.2
Start at 0 and count two spaces to the left to get to the location -2/5 = -0.4
The open hole and the shading to the left indicates the inequality of
x < -0.4
We exclude the endpoint -0.4 because of the open hole.
