Final Answer:
1) X ≥ 195 → point at 195, arrow to the right
2) X > 16 → open circle at 16, arrow to the right
3) X ≤ –40 → solid dot at –40, arrow to the left
4) X ≥ 120 → solid dot at 120, arrow to the right
5) X ≥ 18 → solid dot at 18, arrow to the right
6) X ≥ 60 → solid dot at 60, arrow to the right
7) X > 75 → open circle at 75, arrow to the right
8) X ≥ –100 → solid dot at –100, arrow to the right
9) X ≤ –5 → solid dot at –5, arrow to the left
10) X < 170 → open circle at 170, arrow to the left
11) X > –7 → open circle at –7, arrow to the right
12) X > –5 → open circle at –5, arrow to the right
13) X ≤ 11 → solid dot at 11, arrow to the left
