Imagine you're helping Zoe, Mia, and Isla find the perfect line of best fit for their scatter plot project. Which of the following lines do you think will earn them an A+?

• A

• B

• C

• D

Answer explanation

Line C is the best choice as it closely follows the trend of the data points in the scatter plot, minimizing the distance from the points to the line, which is essential for a strong line of best fit.
