Question 667647: For the table that follows, answer the following questions:
x
y

1
-1/2

2
-1

3
-3/2

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?

x|y

1|-1/2

2|-1

3|-3/2

4|

..........1

..........2
_______________________subtract 1 from 2

..........2

.........the slope- negative
.........now we can find

..........2

so, the equation is:

now, when we see that a slope is negative and is at (,), we know that graph of this line goes through II and IV quadrant,the correlation between and in the table above is negative
the missing value of in the table would be:

here is the graph with all given points on it:
