This is a common core activity for solving systems of equations through graphing. It also allows students to model linear equations from a table of values.
Write a function that describes a relationship between two quantities.
Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.
Represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or non-viable options in a modeling context. For example, represent inequalities describing nutritional and cost constraints on combinations of different foods.
Create equations in two or more variables to represent relationships between quantities; graph equations on coordinate axes with labels and scales.
Create equations and inequalities in one variable and use them to solve problems.
