A parents’ group takes a survey about the number of times their children change clothes in a week. The data are recorded in a table where x represents the age of the child and y represents the number of clothes changes. x 1 1 2 3 3 4 4 5 6 6 y 20 18 17 18 15 12 14 12 11 12 What is the equation of the best-fit line for the data? Use a graphing calculator and round all numbers to the nearest hundredth. A y=−1.59x+20.47y is equal to negative 1 point 5 9 x plus 20 point 4 7 B y=−0.53x+11.45y is equal to negative 0 point 5 3 x plus 11 point 4 5 C y=11.45x−0.53y is equal to 11 point 4 5 x minus 0 point 5 3 D y=20.47x−1.59
