Lessons in this chapter

  1. 1IntroductionMeet the straight-line family: simple rules with surprisingly eventful graphs.
  2. 2Linear PolynomialsA polynomial with just one degree—because not every expression needs drama.
  3. 3Exploring Linear PatternsWhen numbers march in a pattern, algebra quietly learns their choreography.
  4. 4Linear Growth and Linear DecaySome quantities rise, some fall, and linear graphs refuse to overreact.
  5. 5Linear RelationshipsTwo changing quantities finally define the relationship instead of saying, “It’s complicated.”
  6. 6Visualizing Linear RelationshipsPut the relationship on a graph and the pattern stops playing hide-and-seek.
  7. 7Chapter Summary and PracticeCheck whether your linear thinking is still moving in the right direction.
