Question

select the correct answer. how could you adjust the line in this scatter - plot to make it a line of best fit? cellular phones (millions) population (millions) a. increase the y - intercept, and decrease the slope. b. decrease the y - intercept, and decrease the slope. c. decrease the y - intercept, and increase the slope. d. increase the y - intercept, and increase the slope.

Explanation:

Step1: Analyze the current line

The current line has points mostly below it on the left - hand side and above it on the right - hand side.

Step2: Consider y - intercept adjustment

To better fit the points, we need to lower the line at \(x = 0\), so we should decrease the y - intercept.

Step3: Consider slope adjustment

The current line seems to be too flat compared to the overall trend of the points. To fit better, we should increase the slope.

Answer:

C. Decrease the y - intercept, and increase the slope.
