8-9.1 The student uses mathematical processes to acquire and demonstrate mathematical understanding.

8-9.2 The student applies the mathematical process standards when using properties of linear functions to write and represent in multiple ways, with and without technology, linear equations, inequalities, and systems of equations.

8-9.3 The student applies the mathematical process standards when using graphs of linear functions, key features, and related transformations to represent in multiple ways and solve, with and without technology, equations, inequalities, and systems of equations.

8-9.4 The student applies the mathematical process standards to formulate statistical relationships and evaluate their reasonableness based on real-world data.
