Day
Number of
Cars Washed

The car wash owner uses the equation y = x +44 to model the data, where x represents the number
of days the business has been open and y represents the number of cars washed.
Which explanation best describes whether the equation is a good fit for the data?
a The equation is a good fit because the residual points are approximately linear.
The equation is a good fit because the residual points have a positive association
C. The equation is not a good fit because a residual plot with the pattern from this data set
Indicates a bad ſit
The equation is not a good fit because there should be an equal number of points below and
above the x-axis in the residual plot.
D
