Students begin their journey into algebraic graphing by exploring how patterns can be represented as linear relationships. They will learn to create tables of values and translate them into visual lines on a coordinate plane using different equation forms, such as \(y=mx+b\). The chapter also teaches "interpolation" and "extrapolation," which are techniques used to make predictions based on existing data trends. These skills are foundational for understanding how variables change in relation to one another in science and economics
