• D

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

• A

• B

• C

• D

Which line would be the line of best fit?

• Green line (C)

• Orange line (B)

• Purple line (A)

• None of the above

What would be the equation for the line of best fit?

• y = ³/₄x + 9

• y = -¹/₂x + 9

• y = -³/₄x - 9

• y = -³/₄x + 9

y = 1.45x + 22

y = -2x + 15

y = 1.33x + 30

y = -1.5x + 24

• y = 1.45x + 22

• y = -2x + 15

• y = 1.33x + 30

• y = -1.5x + 24
