The best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) 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} \\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
We have a line of best fit shown in the picture.
As we know if the slope of the line is positive then the correlation will be positive.
From the line of best fit:
Because the points are evenly spaced above and below the line, the graph displays a line of best fit.
Thus, the best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.
