A linear regression model is used to show the relationship between variables on a scatter plot
The equation of the linear regression model is: 
and the correlation coefficient is 0.8034
<h3>How to determine the equation of the
linear regression</h3>
The question is incomplete. So, I will make use of a dataset that has the following calculation summary (from a graphing calculator)
- Sum of X = 45
- Sum of Y = 83
- Mean X = 4.5
- Mean Y = 8.3
- Sum of squares (SSX) = 82.5
- Sum of products (SP) = 128.5
- The value of R is 0.8034.
The equation of the linear regression model is:
See attachment for the scatter plot

Answer:
Focus on facts.
Suggest improvements even in positive reviews.
Respond to the business if it offers to address your concern.
Explanation:
In order to establish credibility when posting complaints or reviews, focus must be on fact and must be well supported.
Readers will have more trust in a review that is balanced, therefore one must try to request suggestion for improvement even if the post is positive. Update can be done on original post to effect changes or bring in ideas gotten through communication with the business.
Since the website is permanent, one will be able to edit a post, but not to remove it. Also posts from unknown sources can be tracked, so transparency is needed
