The question, in short

From the given grid and shaded diagram, find the set of inequalities whose solution is the unshaded quadrilateral region R.

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

Solution · 4 marks

  1. 1Sloping side through (1, 1) and (5, 5) is y = x (dashed), R is below it: y < x
  2. 2Vertical side is x = 6 (dashed), R is to its left: x < 6
  3. 3Horizontal sides y = 1 and y = 5 are solid: 1 ≤ y ≤ 5
  4. 4Inequalities: y < x, x < 6, 1 ≤ y ≤ 5

Answery < x, x < 6, 1 ≤ y ≤ 5
