11 On the grid, draw the graph of \(\;y = 3 - 2x\;\) for values of \(x\) from –2 to 3
(3)
| Scheme | Marks |
|---|---|
| (−2, 7) (−1, 5) (0, 3) (1, 1) (2, −1) (3, −3) Answer: Correct line between \(x = -2\) and \(x = 3\) | B3 |
| (3) | |
| (3 marks) |
Notes
B3: for a correct line between \(x = -2\) and \(x = 3\)
(B2 for a correct straight line segment through at least 3 of (−2, 7) (−1, 5) (0, 3) (1, 1) (2, −1) (3, −3)
or
for all of (−2, 7) (−1, 5) (0, 3) (1, 1) (2, −1) (3, −3) plotted but not joined)
(B1 for at least 2 correct points stated (may be in a table) or plotted or for a line drawn with a negative gradient through (0, 3) or for a line with a gradient of −2)
