For the table that follows, answer the following questions:
x y
1 -2
2 -5
3 -8
4
- Would the correlation between x and y in the table above be positive or negative?
- Find the missing value of y in the table.
- How would the values of this table be interpreted in terms of linear regression?
- If a “line of best fit” is placed among these points plotted on a coordinate system, would the slope of this line be positive or negative?

-
A) Negative
B) -11
C) y = -3x + 1
I have graphed it for you at the link below.

-
Negative
-11
the line goes to the right and down like this --> \
negative

-
1.positive
2.-11
3.y=-3x+1 so the value is 1/3
4.negative
2.-11
3.y=-3x+1 so the value is 1/3
4.negative
