The question, in short

Read an inequality from a number line with an open circle at −3 and a rightward 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 for x shown on the number line from −3 to 5 with an open circle at −3 and arrow to the right.

  1. 1The number line shows an open circle at −3 and shading to the right, indicating values greater than −3.
  2. 2So the inequality is x > −3.

Answerx > −3

Part (b) · 2 marks

Solve 4y − 13 ≤ y + 8 for y.

  1. 14y − 13 ≤ y + 8
  2. 24y − y ≤ 8 + 13
  3. 33y ≤ 21
  4. 4y ≤ 7

Answery ≤ 7
