6. Sample response: About 13.4 kilograms ( ). This estimate will probably not be very close. With data only going to 10 oranges, the variability in orange weight will make the estimate harder and harder to get close with more oranges.
7. Sample response: About 1.4 kilograms. The -coordinate estimates the weight of the basket with no oranges in it.
8. Sample response: When there were 4 oranges in the basket, it was closest to my line. I decided because the line almost goes through that point.
9. Sample response: When there were 3 oranges in the basket, it was the worst estimate. I decided since this point is the farthest from the line.
