- 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..
calculator check uses Position vectors: identify the quantities, do the stated operation, and select (4, 6) because it matches the verified final answer.
Maths method check
