Question

which line is the best - fit line for the given data? a. line 1 b. line 2 c. line 3 d. line 4

Explanation:

Step1: Recall best - fit line concept

A best - fit line minimizes the sum of the squared vertical distances between the data points and the line.

Step2: Visually inspect the lines

By looking at the graph, line 4 appears to be closest to most of the data points, minimizing the overall distance from the points to the line.

Answer:

d. line 4
