The answer is 2,911
I would say 2. As the line of best fit is supposed to represent the average of all the data points. It's not nessecarily needed to go through every point.
- 28 - 40i
note that i² = (√-1)² = - 1
expand product of factors using FOIL
= - 6 - 6i - 14i - 14i² - 20i + 36i²
= - 6 - 6i - 14i + 14 - 20i - 36
= - 28 - 40i
