which of the following best approximates the line of best fit?

Explanation:

Step1: Observe the trend of data points

The data - points show a positive linear trend. So, we can rule out option B which has a negative slope.

Step2: Check the closeness of points to the line

The line of best fit should be as close as possible to most of the data - points. Option A has the line passing far away from many points. Option C has the line passing through only a few points. Option D has the line passing close to most of the data - points.

Answer:

D.
