Standard 8.F.B.4 - Identify whether two quantities have a proportional relationship using a coordinate graph.
Included Skills: Graphing
Construct a function to model a linear relationship between two quantities. Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.
