Exam-style question
Try this first
Add the two-dimensional vectors (1, 2) and (3, 4).
- A.(4, 6)
- B.Not (4, 6)
- C.(4, 6) only sometimes
- D.(4, 6) with no working
Model answer
What a good answer should say
- The correct answer is (4, 6).
This answer is tied to the objective: J4 Understand and use position vectors; calculate the distance between two points represented by position vectors..
Explanation
Why this works
Use the explanation to connect the worked answer back to J4 Understand and use position vectors; calculate the distance between two points represented by position vectors..
Use the worked steps as the check: the question intent fixes the answer as (4, 6), and the final-answer line confirms (4, 6).
Maths method check
