To graph x ≤ 600 or x ≥ 900:
- Draw a number line.
- Put a closed dot at 600 and shade the line to the left (including all numbers ≤ 600).
- Put a closed dot at 900 and shade the line to the right (including all numbers ≥ 900).
- The segment between 600 and 900 is not shaded.
Interval notation: (-∞, 600] ∪ [900, ∞)
Example points: 0 and 600 are in the solution; 750 is not; 1000 is in the solution.
