Download 9th Class Math Exercise 5.2 Notes PDF – Linear Inequalities (FBISE 2025)

Exercise 5.2 extends your equation skills into the world of linear inequalities. Instead of hunting a single answer, you’ll describe an entire range of solutions, express it in interval notation, and show it on a number line. FBISE’s 2025 model paper allocated a full five‑mark question to compound inequalities joined by “and/or,” so getting fluent here is an easy mark‑grab. Inside, each concept connects straight back to the official FBISE SLO, then shows how similar questions appeared in BISE Rawalpindi, BISE Multan and BISE Quetta papers. A vertical sidebar legend (“board tags”) lets you track which boards you’ve already practiced. Worked examples escalate from simple x + 5 > 12 to tricky fractional forms requiring sign flips. After every two pages, a one‑minute self‑quiz with QR‑code answers keeps revision lively. We close with a “graph it!” section that shows how to shade inequality solutions on the coordinate plane—a skill that links directly to the Coordinate Geometry unit later in the syllabus.
