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". inches/pounds 60" - 105, 110...
