Exemplars (from the NaCCA curriculum)
E.g.1 Illustrate and explain the inequality signs
E.g.2 Graph linear inequalities in one variable on a number line.
E.g.3 Solve and graph linear inequalities on a number line. i. -3x - 8 > -26 ii. 2x - 3 ≤ 19
2x ≤ 22 2x 22 ≤ 2 2 x ≤ 11 E.g.4 Solve and graph linear inequalities on a cartesian plane. i. 2x ≥ 8 ii. 5y + 3 < 6 + iii. 7x <7 → 3× 7x < 2y 3 3 2x 8 7×3 ≥ 2 2 5y - 2y < 6 - 3 7x 21 < x ≥ 4 3y < 3 7 7 x < 3
∴ y < 1
