The question, in short

Given column vectors v = (−1, 3) and y = (2, 5), carry out the two vector calculations requested.

Summarised in our own words. Use the official paper for the exact wording and any diagrams.

Part (a) · 1 mark

Find v − y as a column vector.

  1. 1v − y = (−1 − 2, 3 − 5)
  2. 2= column vector (−3, −2)

Answercolumn vector (−3, −2)

Part (b) · 1 mark

Find 2v as a column vector.

  1. 12v = (2 × −1, 2 × 3)
  2. 2= column vector (−2, 6)

Answercolumn vector (−2, 6)
