  1. Plot the data in the table on the graph.
  2. ______________ Use a spreadsheet function to calculate the slope of the line.
  3. ______________ Use a spreadsheet function to calculate the y-intercept of the line.
  4. ______________ Calculate the load that could be lifted by a force of 200 gmf.
  5. ______________ Calculate the force required to lift a load of 1600 gmf.
  6. Can this linear relationship be extended to any force or load? Why or why not?
