what is the easiest way to figure this out? pictures attached in comments.

Answer 1

where is picture

Answer 2

JOIN the points.

Answer 3

huh?

Answer 4

Figure what out exactly?

Answer 5

what they ask, the slope and y inter.

Answer 6

So you need to calculate b1 and b0?

Answer 7

Your slope is \[b_{1}=\frac{n(\sum xy) - (\sum x)(\sum y)}{n(\sum x^2) - (\sum x)^2}\] and your intercept is \[b_{0} = \frac{\sum y - b_{1}(\sum x)}{n}\] Giving you a regression line of \(y=b_0 + b_1 x\)
