GCSE Maths Practice: inequalities-on-graphs

Question 6 of 10

This question practices linear inequalities with negative slope and non-strict inequality signs. Students should understand when to use a solid line.

‹ ›

\( \text{Which graph correctly shows the inequality } y \geq -2x + 6? \)

Choose one option:

Use a solid line for non-strict inequalities. Shade above the line for '≥'. Always verify by testing a point not on the line.

For y \geq mx + c, draw the line solid and shade above. This method works for any linear inequality with a non-strict sign. Test a point if unsure.
