Linear graphs and models
This topic includes:
• review of linear functions and graphs
• the concept of a linear model and its specification
• the construction of a linear model to represent a practical situation including domain of application
• the interpretation of the parameters of a linear model and its use to make predictions, including the issues of
interpolation and extrapolation
• fitting a linear model to data by using the equation of a line fitted by eye
• use of piecewise linear (line segment) graphs to model and analyse practical situations.
Inequalities and linear programming
This topic includes:
• linear inequalities in one and two variables and their graphical representation
• the linear programming problem and its purpose
• the concepts of feasible region, constraint and objective function in the context of solving a linear programming
problem
• use of the corner-point principle to determine the optimal solution/s of a linear programming problem
• formulation and graphical solution of linear programming problems involving two variables.
