What is the equation of the line of best fit for the following data? round the slope and y-intercept of the line to three decimal places. x y 4 17 6 12 8 9 11 4 13 3 a. y = 22.105x - 1.560 b. y = 1.560x - 22.105 c. y = -22.105x + 1.560 d. y = -1.560x + 22.105

The table of data is shown below

The equation of line best fit is given in the form 

to find the slope 'm', follow these steps:

STEP 1



STEP 2
Refer to Picture 2 and Picture 3 for the working out of  and 

=(-35.2)+(-7.2)+0+(-13)+(-27.6)=-83

STEP 3:
= 

STEP 4:
To find slope, divide answer in STEP 2 by the answer in STEP 3


STEP 5:



We have the slope,  and y-intercept of 22.105
The equation of line is
