4400 Higher June 2008 Paper 3 Q3
3

(a) Describe fully the single transformation that maps triangle P onto triangle Q. (3)
(b) Describe fully the single transformation that maps triangle P onto triangle R. (2)
| Scheme | Marks |
|---|---|
| Enlargement scale factor 2 centre (1, 3) | B3 |
| (3) |
Notes
B3: B1 for enlargement, enlarge etc
B1 for 2, × 2, two, \(\frac{2}{1}\), 1 : 2, 2 : 1
B1 for (1, 3) Condone omission of brackets but do not accept \(\begin{pmatrix} 1 \\ 3 \end{pmatrix}\)
These marks are independent but award no marks if answer is not a single transformation
| Scheme | Marks |
|---|---|
| Reflection in the line \(y = x\) | B2 |
| (2) | |
| (5 marks) |
Notes
B2: B1 for reflection, reflect etc
B1 for \(y = x\) oe inc eg ‘in line from (2,2) to (5,5)’, ‘in dotted line shown’
These marks are independent but award no marks if answer is not a single transformation
