1.)There is one outlier, indicating very few books were checked out on that day
This is because there is one day where only 2 books were checked out while on all of the other days 35-45 books were checked out.
2.) 0; it represents no correlation between x and y
This is because no matter the age they could answer 17 questions
Hope this helps!

A)
The slope-intercept form:

m - slope
b - y-intercept
The formula of a slope:

We have the points (2, 5.1) and (-1, -0.5). Substitute:

Therefore we have:

Put the coordinates of the point (-1, -0.5) ot the equation:

<em>multiply both sides by 2</em>
<em>add
to both sides</em>
<em>divide both sides by 2</em>

Answer: 
-------------------------------------------------------------------------
B)
We have the points (-2, 3) and (3, -4).
Calculate the slope:

Therefore we have:

Put the coordinates of the point (-2, 3) to the equation of a line:

<em>subtract
from both sides</em>
