On the grid, shade the region R that satisfies all the following inequalities.
\[x \leqslant 2 \qquad y \geqslant -3 \qquad y \leqslant 2x + 1 \qquad 3x + 2y \leqslant 6\]Label the region R. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| Correct region R | M1 | for at least two correct boundaries, eg \(y = -3\) or \(x = 2\) or \(y = 2x + 1\) or \(3x + 2y = 6\) |
| M1 | for the remaining two correct boundaries or a third correct boundary with shading correct with the inequalities for at least two correct boundaries | |
| C1 | for a correct region (R) clearly identified |
