Draw the Line of Best Fit

You plot these points (0,0.5), (1,2), (3,5), (6,7), (10, 8) and draw a scatter plot. If you use the points (2, 3) and (6,6) on the line of best fit to find the equation, which of the following is the equation of the line of best fit?

• y = x

• y = 0.75x + 1.5

• y = x+1

• y = 0.5x+3

Which of the following lines represents the line of best fit for the scatter plot?

• A

• B

• C

• D

Find the equation of the line of best fit for the given data

• y = 163.41x+1.49

• y =- 163.41x+ 4.19

• y =- 4.19x+163.41

• y = 4.19x -163.41

• y = 1.45x + 22
• y = -2x + 15
• y = 1.33x + 30
• y = -1.5x + 24
