17 The graphs of \(y = x\) and \(y = -2\) are drawn on the grid.
The region R satisfies the following inequalities.
\(y \geqslant -2\) \(y \leqslant x\) \(y \lt 4 - 2x\)
By drawing one more line, find and label the region R. [5]
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
 | 5 | B2 for \(y = 4 - 2x\) broken line or B1 \(y = 4 - 2x\) solid line AND B1FT for \(R\) correct side of \(y = 4 - 2x\) B1 for \(R\) correct side of \(y = -2\) B1 for \(R\) correct side of \(y = x\) | See marks on diagram for next 3 marks Grid assumes \(y = 4 - 2x\) is correct FT dep on sloping line drawn |
