The question, in short
On a grid spanning x from −5 to 6 and y from −4 to 7, shade and label R for the area meeting x ≤ 4, y ≥ −2 and y ≤ x.
Summarised in our own words. Use the official paper for the exact wording and the diagram.
Solution · 3 marks
- 1Draw the line y = x as a solid line
- 2Draw the line x = 4 as a solid line
- 3Draw the line y = −2 as a solid line
- 4Shade the region where x ≤ 4, y ≥ −2 and y ≤ x
- 5Label the unshaded (or shaded) region as R
AnswerRegion R identified by shading bounded by x = 4, y = −2 and y = x
