Answer
Interval Notation: (-infinity, -0.2)
Number Line: Closed circle on -0.2, entire left side of -0.2 on number line is shaded excluding -0.2
Work Step by Step
Because x < -0.2,
-0.2 is not included in the number line.
Therefore, the solution will include all values that are to the left of -0.2 on the number line, excluding -0.2.
The interval notation uses open brackets on -0.2 and infinity because they are not included in the solution.
