Predictions from Best-Fit Lines

Calculate the value of a response variable using a least-squares line.

By observing a set of data values, Thomas used a calculator for the weight (in pounds) and predicted the number of calories burned per minute to get an equation for the least-squares line:

= 2.2 + 0.05x.

Based on the information gathered by Thomas, select the statement that is TRUE.

• a.)
• A person weighing 173 pounds can burn 10.7 calories per minute.
• b.)
• A person weighing 149 pounds can burn 9.8 calories per minute.
• c.)
• A person weighing 125 pounds can burn 8.3 calories per minute.
• d.)
• A person weighing 134 pounds can burn 8.9 calories per minute.
