The question, in short

Read an inequality from a number line from −3 to 5 with an open circle at −3 and a right-pointing arrow, then solve 4y − 13 ≤ y + 8.

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

Part (a) · 1 mark

State the inequality represented by the number line, which has an open circle at −3 and an arrow pointing right.

  1. 1Open circle at −3 means −3 is not included
  2. 2Arrow goes right, so values greater than −3
  3. 3x > −3

Answerx > −3

Part (b) · 2 marks

Solve 4y − 13 ≤ y + 8 for y.

  1. 14y − y ≤ 8 + 13
  2. 23y ≤ 21
  3. 3y ≤ 7

Answery ≤ 7
