(a) Complete the table of values for \(\;y = 3x - 1\)
(2)
| \(x\) | −1 | 0 | 1 | 2 | 3 | 4 | 5 | 6 |
|---|---|---|---|---|---|---|---|---|
| \(y\) | −1 | 5 | 14 |
(b) On the grid, draw the graph of \(\;y = 3x - 1\;\) for values of \(x\) from −1 to 6
| Scheme | Marks |
|---|---|
| −4, (−1), 2, (5), 8, 11, (14), 17 | B2 |
| (2) |
Notes
B2: for −4, 2, 8, 11, 17
(B1 for 3 or 4 correct values)
| Scheme | Marks |
|---|---|
| M1 | |
| Graph drawn | A1 |
| (2) | |
| (4 marks) |
Notes
M1: (may ft from (a) if B1 awarded) for at least 5 points correctly plotted – if no plots, use points at which graph crosses squares or M1
A1: for correct graph drawn from \(x = -1\) to \(x = 6\)
