<span>Linear regression is a method of finding the linear equation that comes closest to fitting a collection of data points.
</span>The better the choice of line, the closer the predicted values will be to the observed values. 
The differences between the data pints (observed values) and the estimated (pedicted) regression line is called  the <span>residue.
</span>Residue = Observed Value -<span> Predicted Value</span>
        
             
        
        
        
Answer:
x = 5.5
y = - 6.5
Step-by-step explanation:
Let one of the numbers = x
Let the other number = y
x + y = - 1
x = y + 12    Put the second equation into the first one
y + 12 + y = - 1       Subtract 12 from both sides
y + y = - 1 - 12        Combine both left and right sides
2y = - 13                Divide by 2
2y/2 = - 13/1
y = - 6.5
x + y = - 1
x - 6.5 = - 1            Add 6.5 to both sides
x = 5.5
