14 On the grid, draw the graph of \(\quad y = 2x - 6 \quad\) for values of \(x\) from \(-2\) to 5 [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| Any two of \((-2, -10)\), \((-1, -8)\), \((0, -6)\), \((1, -4)\), \((2, -2)\), \((3, 0)\), \((4, 2)\), \((5, 4)\) | M1 | two correct pairs of coordinates may be in a table implied by points plotted \(\pm\) 2 mm |
| At least two correct points plotted or At least two of their points plotted correctly | M1 | implied by correct line of any length \(\pm\) 2 mm |
| Straight line from \((-2, -10)\) to \((5, 4)\) | A1 | ignore line outside the domain \([-2, 5]\) |
