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?

the slope of the line of best fit would be negative too i think

idk 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

When x = 4, y is... y = 4x + 3 y = 4(4) + 3 y = 16 + 3 y = 13 So when x = 4, y is y = 13

Thank you jim I have been on this stupid problem for over 4 hours trying to figure out the equation to use for it. Thank you so much
