Answer:
The linear regression model is [tex]y=-2.19x-8.92[/tex].
Step-by-step explanation:
The given data points are (-6 4) (-4 0) (-3 -2) (-1 -7). Plot these points on a coordinate plane.
From the graph it is clear that the point are in the form of a straight line, so we need to use the linear regression model.
The general linear regression model is
[tex]y=ax+b[/tex]
Using technology we get
[tex]a=-2.1923076923\approx -2.19[/tex]
[tex]b=-8.9230769231\approx -8.92[/tex]
Put a=-2.19 and b=-8.92 in the above equation.
[tex]y=-2.19x-8.92[/tex]
Therefore the linear regression model is [tex]y=-2.19x-8.92[/tex].
