Shape P is reflected in the line \(x = -1\) to give shape Q.
Shape Q is reflected in the line \(y = 0\) to give shape R.
Describe fully the single transformation that maps shape P onto shape R. (3)
| Working | Answer | Mark | Notes |
|---|---|---|---|
| Q at \((-3, 1)\), \((-6, 1)\), \((-5, 3)\), \((-3, 3)\) R at \((-3, -1)\), \((-6, -1)\), \((-5, -3)\), \((-3, -3)\)  | Rotation \(180^\circ\) about \((-1, 0)\) | 3 | M1 for showing R correctly on the grid without showing Q or for showing Q and R correctly on the grid A1 for rotation of \(180^\circ\) A1 for (centre) \((-1, 0)\) Or M1 for showing R correctly on the grid without showing Q or for showing Q and R correctly on the grid A1 for Enlargement Scale Factor \(-1\) A1 for centre \((-1, 0)\) NB Award no marks for any correct answer from an incorrect diagram or any Accuracy marks if more than one transformation is given |
