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?

As x increases y decreases. Therefore the slope is negative.
Each unit increase in the value of x results in the value of y decreasing by 1/2. Therefore the missing value of y is (-3/2 - 1/2) = -2
The values of the table form a negatively correlated straight line.
When a "line of best fit" joins the points the slope is negative.

@mzbuttacup I'm unable to focus on "Best fit" due to your icon is the WORST fit!
