9. +-13 points JKEStat10 3.E.057 My l The values of x used to find points for graphing the line y = 15 + 0.6x are arbitrary. Suppose you choose to use x-23 and x = 45. (a) What are the corresponding ý values? (Give your answers correct to one decimal place.) x 23) (x = 45) (b) Are these points on the line of best fit? Explain why or why not. O Yes, the line of best fit is made up of all points that satisfy its equation. O No, they do not satisfy the criteria for the line of best fit. O No, the line of best fit is made up of all the points that are in a data set. O Yes, because they are reasonable values. Submit Answer LSave Progress] | Practice Another Version

Explanation / Answer

a)for x=23

corresponding yhat =15+0.6*23=28.8

for x=45

corresponding yhat =15+0.6*45=42

b)

Yes the line of best fit is made up of all points that satisfy its equation
