Question

Graph the set of points. which model is most appropriate for the set (-6 4) (-4 0) (-3 -2) (-1 -7)

Answer 1

Answer:

The linear regression model is $y=-2.19x-8.92$.

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

$y=ax+b$

Using technology we get

$a=-2.1923076923\approx -2.19$

$b=-8.9230769231\approx -8.92$

Put a=-2.19 and b=-8.92 in  the above equation.

$y=-2.19x-8.92$

Therefore the linear regression model is $y=-2.19x-8.92$.
