The data below represents height in inches/weight in pounds.
Clearly identify the dependent and independent variables as well as
the domain and range. Choose any two points from the data using
different independent variables and use those two points to
determine the rate of change (slope). Then, using the dependent
data value of -500 as your initial value, write an equation for the
linear function model. Predict what you expect at a height of
75".
