4. Linear Equations and Inequalities | 线性方程与不等式
Solving linear equations with unknowns on both sides and those involving brackets is a core skill. Students tackle fractional equations and learn to verify their solutions by substitution.
求解未知数在两侧及含有括号的线性方程是核心技能。学生解决含有分数的方程，并学会通过代入法检验解。
Simultaneous linear equations are solved both algebraically (elimination and substitution) and graphically, with attention to setting up equations from word problems. The concept of intersection is linked to real-world break-even points.
联立线性方程通过代数法（消元法和代入法）及图像法求解，并关注从文字题中建立方程组。交点的概念与实际盈亏平衡点联系起来。
Inequalities are introduced and represented on number lines. Students learn to solve linear inequalities and represent solution sets using set builder notation and interval notation, as well as graphing regions defined by inequalities in two variables.
引入不等式并在数轴上表示。学生学会解线性不等式，使用集合构造式记号和区间记号表示解集，并绘制由两个变量不等式定义的区域。
5. Graphing Linear and Quadratic Functions | 线性与二次函数图像
c. Students explore parallel and perpendicular lines, linking algebraic and geometric properties.
