Answer

Explanation:

Step1: Visualize trend line

Draw an approximate trend - line through the data points on the scatter - plot.

Step2: Predict weight for 20 items

For Kylie with 20 items, follow the vertical line at 20 on the x - axis (number of items) up to the trend - line and then across to the y - axis (total weight). The value is around 26 lbs.

Step3: Predict number of items for 40 lbs

For Beau's 40 - pound suitcase, follow the horizontal line at 40 on the y - axis up to the trend - line and then down to the x - axis. The number of items is around 40. The value 31 is not a reasonable prediction as it is far from the trend.

Answer:

  1. d. 26 lbs
  2. c. 31
