9 Show, by shading on the grid, the region which satisfies these inequalities
\(1 \leqslant x \leqslant 3 \quad\) and \(\quad -4 \leqslant y \leqslant -2\)
Label your region \(\mathbf{R}\).
(3)
| Scheme | Marks |
|---|---|
| \(\mathbf{R}\) shown | B3 |
| (3) | |
| (3 marks) |
Notes
B3: for correct \(\mathbf{R}\) shaded in or out
Condone omission of label
B2: for single shaded shape with 3 correct boundaries or for parts of both regions unambiguously shown or for 3 or 4 correct lines + 0 incorrect
B1: for single shaded shape with 2 correct boundaries or for square parts of both regions ambiguously shown or for 2, 3 or 4 correct lines + one or more incorrect
SC B1: for region bounded by \(1 \leqslant y \leqslant 3\) and \(-4 \leqslant x \leqslant -2\)
