The scatter plot shows the association between the ordered pairs

The two ordered pairs that can be joined to best draw the line of best fit for this scatter plot are (0, 13) and (10, 0)

<h3>How to determine the two best ordered pairs?</h3>

To draw the line of best fit, the line must pass through at least two points such that the number of points on either sides of the line must be equal

See attachment for illustration

From the attached image of the graph, we can see that the line passes through the points (0, 13) and (10, 0), and there are 4 points on either sides

Hence, the two ordered pairs are (0, 13) and (10, 0)

To determine the distance between two points, we use the equation,
                                   distance = √(x₂ - x₁)² + (y₂ - y₁)²
Substituting the known values for the abscissa and ordinates of the points,
                                distance = √(0 - 2)² + (0 - 5)² = √29 ≈ 5.39 
Therefore, the distance between these two points is approximately equal to 5.39.
