What's on the worksheet

  1. Decide if each table could come from a linear function and write the rule:
    x: 1, 3, 4, 7 \quad y: 5, 11, 14, 23x: 2, 6, 8, 14 \quad y: 13, 11, 10, 7x: −5, −2, 1, 3 \quad y: 13, 7, 1, −4x: 0.5, 1.5, 2, 3.5 \quad y: 4, 6.5, 7.75, 11.5x: 4, 10, 16, 22 \quad y: 1, 5, 9, 13
  2. Check Kevin's claim that outputs going up by the same amount means linear.
  3. Word problem: the height of a bamboo shoot measured each day.
  4. Word problem: seats in the rows of a theater.
  5. Explain why Mei's different ratios of output to input do not mean the table is not linear.
