No Pre-reading question
Textbook Reading: Walker, section 2-7 (pages 39-41, INCLUDING the Conceptual Checkpoint). Then, take a careful look at example 2-11 on pages 41-42. The problem-solving note on p.41 is also pretty helpful.
Post-reading: Try question 77 on page 53. You’ll need a ruler.
Other study notes: We’ve now covered everything in chapter 2, so all the material in it is fair game for the quiz. You should look over the chapter summary on pages 45-47.
