Higher June 2025 Paper 3 Q19
19 On the grid, identify the region represented by
\[x + y \lt 5 \quad \text{and} \quad y \lt 2x + 4 \quad \text{and} \quad y \geqslant 1\]Label the region R. [4 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(x + y = 5\) and \(y = 2x + 4\) drawn as dashed line and \(y = 1\) drawn as a solid line and correct region identified | B4 | B3 \(x + y = 5\), \(y = 2x + 4\) and \(y = 1\) drawn as dashed or solid lines B2 two of \(x + y = 5\), \(y = 2x + 4\) and \(y = 1\) drawn as dashed or solid lines B1 \(x + y = 5\) or \(y = 2x + 4\) or \(y = 1\) drawn as dashed or solid line |
Additional guidance
Allow any unambiguous identification of the correct region, eg labelled R or shaded in or shaded out
If there are more than three lines plotted, treat as choice for positive gradients, negative gradients or horizontal/vertical lines. A shaded region may imply the chosen lines
Mark intention for straight lines
