Question

A regression 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.

Answer 1

Therefore the slope of

`y= -3.2x + 9.7`

is

`Slope =-3.2`

Explanation:

Given:

A regression line was calculated as

`y= -3.2x + 9.7`

To Find:

Slope = ?

Solution:

General Slope-Point Form is given as

`y=mx+c`

Where,

`m=Slope\\c=y-intercept`

On Comparing with given Regression line we get

`Slope = m = -3.2`

Therefore the slope of

`y= -3.2x + 9.7`

is

`Slope =-3.2`
