Mr. Dylan asks his students throughout the year to record the number of hours per week they spend practicing math at home. At the end of the year, he creates a scatter plot that models the relationship between exam score and time spent practicing. Which line of best fit will give Mr. Dylan the most accurate linear equation in order to make predictions about this relationship?

Here's what I get  

Step-by-step explanation:

Assume the scatter plot looked like the one below.

The line of best fit should go as close as possible to all the points without necessarily going through any of them.

Also, the points should be scattered relatively evenly on each side of the line.

The figure shows the best-fit line, with about half the points above it and half below it.

It will give Mr. Dylan the most accurate equation for predicting the student's grades.
