The question, in short
From a number line diagram, state the inequality shown; then identify the least whole number meeting a given strict inequality involving −3 1/4.
Summarised in our own words. Use the official paper for the exact wording and any diagrams.
Part (a) · 2 marks
Give the inequality matching the number line, which has a solid dot at −4 and a hollow dot at 3 joined by a segment.
- 1Filled circle at −4 means −4 is included: −4 ≤ x
- 2Open circle at 3 means 3 is not included: x < 3
- 3−4 ≤ x < 3
Answer−4 ≤ x < 3
Part (b) · 1 mark
State the lowest integer value of d that makes d > −3 1/4 true.
- 1−3 1/4 = −3.25; the next integer above −3.25 is −3
- 2Smallest integer d = −3
Answer−3
