Question

An airport terminal runs shuttle buses to different parts of the airport. The scatter plot shows the times for each part of the airport and a number of round trips. Which equation is closest to the line of best fit for this data

Answer 1

The closest line that I would suggest would be choice A.  

I used the points (1, 2) and (7, 5) to create my line. That gives a slope of 1/2 and a w-intercept of 1.5.

The closest fit would be A where the slope is 3/5 and the y-intercept is 1.

Choice C is very close also.
