Aregression line was calculated as ŷ = -3.2x + 9.7. determine the slope of this line. type a numerical answer in the provided space. do not type spaces in your answer.

Therefore the slope of

is

Step-by-step explanation:

Given:

A regression line was calculated as

To Find:

Slope = ?

Solution:

General Slope-Point Form is given as

Where,

On Comparing with given Regression line we get

Therefore the slope of

is

idk

step-by-step explanation:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
