Points (−6, 3) and (−6, −3) on the coordinate grid below show the positions of two dogs at a park: A coordinate plane is shown. There is a point at negative 6, 3 labeled Dog 1. There is a point at negative 6, negative 3 labeled Dog 2. Which statement best describes the relationship between the positions of the two players?

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes
