Which equation best fits the data?

• y = -0.1x + 110
• y = -0.1x
• y = 0.1x + 110

• (65 height, 10 volume)
• (74 height, 20 volume)

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.
