Answer 1

Your work is correct except for a wording slip in Part 5.

- Slope = -0.4 (thousand people per °F).
- Each 1°F increase → 0.4 thousand = 400 fewer people.
- Temperature change 80 − 60 = 20°F.
- Change = -0.4 × 20 = -8 (thousand) → -8,000 people.

So about 8,000 fewer people are predicted at 80°F than at 60°F (not "8,000 thousand").
