GCSE Maths Practice: inequalities-on-graphs

Question 10 of 10

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

‹

\( \text{Which graph correctly shows the inequality } y \leq 4x - 1? \)

Choose one option:

Use a solid line for '≤'. Shade correctly below the line. Verify by testing a point not on the line.

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