(3)
| Scheme | Marks |
|---|---|
| (−1, −5)(0, −3)(1, −1)(2, 1)(3, 3)(4, 5)(5, 7) Answer: Correct line between \(x = -1\) and \(x = 5\) | B3 |
| (3) | |
| (3 marks) |
Notes
B3: For a correct line between \(x = -1\) and \(x = 5\)
B2 for a correct line through at least 3 of (−1, −5)(0, −3)(1, −1)(2, 1)(3, 3)(4, 5)(5, 7) OR for all of (−1, −5)(0, −3)(1, −1)(2, 1)(3, 3)(4, 5)(5, 7) 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 gradient of 2
