The question, in short
Given column vectors BA = (−5, 4) and BC = (9, 1), find the column vector AC.
Summarised in our own words. Use the official paper for the exact wording and any diagrams.
Solution · 2 marks
- 1AC = AB + BC
- 2AB is BA reversed, so AB = −(−5, 4) = (5, −4)
- 3AC = (5, −4) + (9, 1)
- 4AC = (5 + 9, −4 + 1) = (14, −3)
Answer(14, −3)
