(3)
| Scheme | Marks |
|---|---|
| (–1, 6) (0, 4) (1, 2) (2, 0) (3, –2) (4, –4) Correct answer scores full marks (unless from obvious incorrect working) Answer: For a correct line between \(x = -1\) and \(x = 4\) | B3 |
| (3) | |
| (3 marks) |
Notes
B3: For a correct line between \(x = -1\) and \(x = 4\)
B2 For a correct straight line segment through at least 3 of (–1, 6) (0, 4) (1, 2) (2, 0) (3, –2) (4, –4)
OR
for all of (–1, 6) (0, 4) (1, 2) (2, 0) (3, –2) (4, –4) plotted but not joined
OR
for a line drawn with a negative gradient through (0, 4) and clear intention to use a gradient of –2
B1 For at least 2 correct points stated (may be in a table)
OR
for a line drawn with a negative gradient through (0, 4)
OR
for a line with a gradient of –2
