(3)
| Scheme | Marks |
|---|---|
| (−2, −1) (−1, 1) (0, 3) (1, 5) (2, 7) (3, 9) (4, 11) Answer: Correct line between \(x = -2\) and \(x = 4\) | B3 |
| (3) | |
| (3 marks) |
Notes
B3: For a correct line between \(x = -2\) and \(x = 4\)
B2 for a correct line through at least 3 of (−2, −1) (−1, 1) (0, 3) (1, 5) (2, 7) (3, 9) (4, 11) OR for all of (−2, −1) (−1, 1) (0, 3) (1, 5) (2, 7) (3, 9) (4, 11) plotted, not joined.
B1 For at least 2 correct points stated (may be in a table) OR for a line drawn with a positive gradient through (0, 3) OR for a line with the correct gradient.
