Leroy has led the story hour at Deer Creek Library every week for the past few months. This scatter plot shows the number of children who attended each story hour and the total number of books they checked out during that story hour. The scatter plot also shows the line of best fit.
The equation for the line of best fit is y=3x+1. According to the equation, which of these statements is true?
According to the equation y = 3x + 1, it means that for every additional child attending the story hour (x increasing by 1), the total number of books checked out (y) increases by 3.
Therefore, the statement that is true is: "For every additional child attending the story hour, an average of 3 books are checked out."
