Graph the set of points. which model is most appropriate for the set (-6 4) (-4 0) (-3 -2) (-1 -7)
Free_Kalibri [48]

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.

What is the rate of change of the linear relationship modeled in the table?
Lisa [10]
The correct answer is 3/2.

Slope = Rate Of Change 

Slope Formula:        y₂ - y₁          5 - 2         3
                               -------------- = ---------- = -----
                                   x₂ - x₁          3 - 1         2

I hope that this helps you!

Btw, ₁ and ₂ are subscripts, they do not have anything to do with the actual working of the problem.
