What examiners said
Those who found the value of k first had slightly easier arithmetic. Matrix multiplication was usually done well. In questions of this type candidates should show the result of multiplying together one pair of matrices before going on to multiply by the third.
— Examiner report, October/November 2023, 9231/11 Q5(a) (Cambridge)
This question was answered well with very few looking for invariant points or considering lines that do not pass through the origin.
— Examiner report, October/November 2023, 9231/11 Q5(b) (Cambridge)
Candidates clearly know the form of the matrices representing enlargement and one-way stretch. A few found the matrix for reflection more difficult. Problems arose when candidates used the same unknown in both D and E and so were unable to solve their equations. Usually, the question was well answered.
