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
