Alaska Mathematics Standards Grade 8 Grade Level/Course 8 Domain Functions Cluster Define, evaluate, and compare functions. 8.F.1 Understand that a function is a rule that assigns to each input (the domain) exactly one output (the range). The Standard graph of a function is the set of ordered pairs consisting of an input and the corresponding output. For example, use the vertical line test to determine functions and non-functions.

Identify cases in which a system of two equations in two unknowns has no solution. Identify cases in which a system of two equations in two unknowns has an infinite number of solutions. Solve a system of two equations (linear) in two unknowns algebraically. Solve simple cases of systems of two linear equations in two variables by inspection.
