Knowledge

Students know:

How to construct a linear function that models the relationship between two quantities.
Graph linear equations.
That the graph of a function is the set of ordered pairs consisting of input and a corresponding output.
That the graph of a two-variable equation represents the set of all solutions to the equation.

Skills

Students are able to:
