## MA 105: Scatter Plot Investigation

- Create a scatter plot of the data from one of tables 3.28-3.31.
- Is this data linear?

- If so, draw the line of best fit. If not, explain why not.

- If the data is linear, find the equation of the line of best fit.

- If you have time, enter the data into your computer (or calculator) and find the line of
best fit predicted by the computer.

- Is the computer model as good as, better than, or worse than
your model? Why?
