GCSE Maths Practice: inequalities-on-graphs

Question 7 of 10

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

‹ ›

\( \text{Which graph correctly shows the inequality } y \geq 2x - 1? \)

Choose one option:

Use a solid line for '≥'. Shade correctly above the line. 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.
