Lines Slope

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

• A

• B

• C

• D

Which line appears to fit the data better?

• line A

• line B

If m = 8/5 and b = -8/5, what is the equation of the trend line in y= mx + b?

• 0 = 8/5 (1) - 8/5

• y = -8/5 x + 8/5

• y = 8/5 x - 8/5

• y = mx + b

If m = -3/4 and b = 9, what is the equation of the trend line in y= mx + b?

• 0 = -3/4 (9) +9

• y = -3/4 x + 9

• y = -3/4 x - 9

• y = 3/4 + 9
