Question
Use a checking method for this problem: final-answer check: add the vectors (23, 25) and (23, -22). State the final answer and verify it against the information in the question.
Answer
A valid checked answer is (46, 3). The method is: A vector calculation works component by component. Add the x-components. The x-component is 46. The y-component is 3. (46, 3) The final line agrees with the canonical answer.
Explanation
calculator check keeps the canonical answer (46, 3) fixed before the model answer is written, so the worked solution and final answer agree.
Common mistake
Translations as vectors common mistake 1
Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Describe translations as two-dimensional vectors..
Show the method first, then give the final answer in the required form. Apply this directly to Translations as vectors.
