Calculating Line of Best Fit from Tables

The table shown is comparing a person's foot length to their height in cm. Calculate a line of best fit.

• f(x) = 25.05x + 5.57

• f(x) = 127x + 25.05

• f(x) = -127x + 25.05

• f(x) = 127x - 25.05

Find the line of best fit.

• y = -0.96x + 0.78

• y = 0.66x - 0.89

• y = -2x + 2

• y = 2x - 2

Find the line of best fit

• y = 6.3x + 62

• y = 62x + 6.3

• y = 3x + 84

• y = 84x + 3

Find the line of best fit

• y = 0.20x + 26

• y = 26x + 0.20

• y = 25x + 28

• y = 28x + 25

Is this line an accurate line estimate of best fit for the data?

• Yes

• No

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

Calculate the line of best fit.

• y = 510x + 8750

• y = 8750 + 510x

• y = 3x + 10700

• y = 10700x + 3

Find the line of best fit

• y = -5.4x + 10840

• y = 10840x - 5.4

• y = 2001x + 39

• y = 39x + 2001

Find the line of best fit

• y = 1.2x + 22

• y = 22x + 1.2

• y = 12x + 47

• y = 47x + 12

Find the line of best fit

• y = 0.42x - 20

• y = -20x + 0.42

• y = 67x + 8.5

• y = 8.5x + 67
