Use the following table to answer the questions. (Give your answers correct to two decimal places.)

x 1 1 3 3 5 5 7 7 9 9
y 3 2 6 1 3 3 3 2 5 3

(a) Find the equation of the line of best fit.
y hat = 2.6+.1x

(b) Find the ordinates y hat for the points on the line of best fit whose abscissas are x = 1, 3, 5, 7, and 9
Not sure how to do these, I first did half of them and that was wrong.
