Consider the plot created from the residuals of a line of best fit for a set of data.

Does the residual plot show that the line of best fit is
appropriate for the data?

O Yes, the points have no pattern,
O Yes, the points are evenly distributed about the x-
axis
O No, the points are in a linear pattern,
O No, the points are in a curved pattern.

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.
