Question

determine which of the lines best represents the line of fit for the data.
a. line b
b. line c
c. line d
d. line a

Explanation:

Step1: Understand the concept of line of fit

A line of fit should pass through the middle of the data points, showing the general trend of the data.

Step2: Analyze each line

• Line A: It does not pass through the middle of the data points.
• Line B: It passes through the middle of the data points, showing the general trend of the data.
• Line C: It is a vertical line, which is not a valid line of fit (a line of fit should be a non - vertical straight line to show the relationship between two variables).
• Line D: It is a vertical line, which is not a valid line of fit.

A. Line B
