Interpreting Slope in a Line of Best FitUse the scatterplot and equation to answer the question.A graph with number of hours on the x-axis and number of customers served on the y-axis. A trend line has equation y = 17.9 x + 6.67.The data reflects the number of hours an employee spends working a checkout line (x), paired with the number of customers served (y). How can the slope of the line be interpreted?With each additional hour, between 6 and 7 customers are served.With each additional hour, nearly 18 customers are served.Each additional customer requires 17.9 minutes to check out.Each additional customer requires 6.67 minutes to check out.
