Scatter Plots

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

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 = -0.96x + 0.78

• y = 0.66x - 0.89

• y = -2x + 2

• y = 2x - 2

Select the statement that best describes the line.

• The line is the line of best fit.
• The line is NOT a line of best fit because it does not pass through two points.
• The line is NOT a line of best fit because it does not go through the middle of the data set.
• The line is NOT a line of best fit because it does not go through the origin.
