For the table that follows, answer the following questions: x y 1 1 2 5 3 9 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?

Best ResponseYou've already chosen the best response.0idk why you're going through all this trouble with regression when all points lie on the same line...namely y = 4x + 3 How did I get this? As you increase x, y is decreasing by 4 each time. So the slope is 4/1 = 4 So y = mx + b y = 4x + b 1 = 4(1) + b 1 = 4 + b 1 + 4 = b 3 = b b = 3 So the equation of the line is y = 4x + 3 You can check this by plugging in x = 1 to get y = 4x + 3 y = 4(1) + 3 y = 4 + 3 y = 1 So when x = 1, y is y = 1 Now plug in x = 2 to get y = 4x + 3 y = 4(2) + 3 y = 8 + 3 y = 5 So when x = 2, y is y = 5 Finally, plug in x = 3 to get y = 4x + 3 y = 4(3) + 3 y = 12 + 3 y = 9 So when x = 3, y is y = 9

Best ResponseYou've already chosen the best response.0When x = 4, y is... y = 4x + 3 y = 4(4) + 3 y = 16 + 3 y = 13 So when x = 4, y is y = 13
