(a) On the number line, show the inequality \(-2 \leqslant y \lt 1\)
\(n\) is an integer.
(b) Write down all the values of \(n\) that satisfy \(-3.4 \lt n \leqslant 2\) (2)
| Scheme | Marks |
|---|---|
| Correct number line | B2 |
| (2) |
Notes
B2: for a fully correct number line e.g. shaded circle at \(-2\), unshaded circle at 1 and a line drawn between them
(B1 for a shaded circle at \(-2\) or an unshaded circle at 1 or circles at \(-2\) and 1 with line in between but shading incorrect)
| Scheme | Marks |
|---|---|
| \(-3, -2, -1, 0, 1, 2\) | B2 |
| (2) | |
| (4 marks) |
Notes
B2: fully correct values with no extras
(B1 for 5 correct values and none incorrect or all 6 correct values with no more than one additional incorrect value)
