Math Problem Statement
Look at the data graphed on the scatter plot below. Which of these shows the line of best fit for the data in the scatter plot?
Solution
The scatter plot shows a positive linear trend. A line of best fit would start around (1, 1) and end around (10, 8), roughly passing through the center of the data points. It should balance the points above and below the line.
