Higher November 2021 Paper 2 Q18
18 On the grid, identify the region represented by
\(x \leqslant 5 \qquad y \leqslant 4 \qquad x + y \gt 6\)
Label the region R. [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(x = 5\) and \(y = 4\) drawn as solid lines and \(x + y = 6\) drawn as dashed line and correct region identified | B3 | B2 \(x = 5\) and \(y = 4\) drawn as solid lines and \(x + y = 6\) drawn as dashed line and correct region not identified or \(x = 5\) and \(y = 4\) and \(x + y = 6\) drawn as solid or dashed lines and correct region identified B1 \(x = 5\) and \(y = 4\) drawn as solid or dashed lines or \(x + y = 6\) drawn as solid or dashed line |
Additional guidance
Allow any unambiguous identification of the correct region
eg Labelled R or shaded in or shaded out
Mark intention for straight lines
