Graph (A) shows the best fit of the line because it has a positive slope and the line is very close to the dots, option (A) is correct.
What is the line of best fit?
A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}[/tex]
[tex]\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
We have a dot plot shown in the picture.
As we can see in the given picture, the values of independent and dependent variables increase, which means the slope of the line should be positive.
In graph (A) the line of the best fit is very close to the dots and best describes the data.
Thus, graph (A) shows the best fit of the line because it has a positive slope and the line is very close to the dots option (A) is correct.
