| Scheme | Marks | AO |
|---|---|---|
 | M1 M1 A1 | 1.1 1.1 1.1 |
| [3] |
Notes
M1: \(y = 2x - 3\) correct in first quadrant; may be implied by reflection or by A1
M1: reflection of their straight line to form V shape for positive \(y\) only
A1: symmetrical V shape through (0,3) with vertex at (1.5, 0) ; points may be identified from numbered scale or written separately
condone branches of different lengths
