Summarised in our own words. Use the official paper for the exact wording and the diagram.
Solution · 3 marks
- 1Work out points: x = −2 gives y = −7, x = 0 gives y = −3, x = 4 gives y = 5
- 2Plot the points, including (−1, −5), (1, −1), (2, 1) and (3, 3)
- 3Join them with a ruler: a straight line from (−2, −7) to (4, 5)
Answerline y = 2x − 3 drawn from (−2, −7) to (4, 5)
