Higher November 2018 Paper 1 Q14
14. On the graph paper below, draw the region which satisfies all of these inequalities.
\(y \geqslant -2\) \(y \geqslant 2x - 4\) \(y \lt 4 - x\) \(x \geqslant -1\)
Indicate clearly the region that is your answer. [4]
| Scheme | Marks | Comments |
|---|---|---|
| Lines \(x = -1\) AND \(y = -2\) drawn correctly | B1 | |
| Line \(y = 2x - 4\) drawn correctly | B1 | |
| Line \(y = 4 - x\) drawn correctly | B1 | Allow solid line used for this mark only |
| Region indicated with correct marking of boundaries | B1 | \(y = 4 - x\) must be shown as dotted or indicated that it is not included. FT ‘their 4 lines’ provided at least B2 previously awarded.  |
