Use variables to represent two quantities in a real-world problem that
change in relationship to one another; write an equation to express
one quantity, thought of as the dependent variable, in terms of the
other quantity, thought of as the independent variable. Analyze the
relationship between the dependent and independent variables using
graphs and tables, and relate these to the equation. For example, in a
problem involving motion at constant speed, list and graph ordered pairs
of distances and times, and write the equation d = 65t to represent the
relationship between distance and time.
