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

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
