The question, in short
A number line from −2 to 5 has a filled circle at −1.5 joined to an open circle at 4; write the inequality in y that it represents.
Summarised in our own words. Use the official paper for the exact wording and any diagrams.
Solution · 2 marks
- 1Filled circle at −1.5 means −1.5 is included: −1.5 ≤ y
- 2Open circle at 4 means 4 is not included: y < 4
- 3−1.5 ≤ y < 4
Answer−1.5 ≤ y < 4
