Construct functions to model linear relationships between two quantities

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.


  • Determining the constant rate of change

    In this lesson you will learn calculate the rate of change of a linear function by examining the four representations of a function.
