4. 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
Interpreting rate of change and initial valueThe rate of change (slope) and initial value (yintercept) can be found from graphs, tables, equations, and verbal explanations.
