1. I think the distance is 5 miles because the y-axis points for both coordinates are the same, and the difference between the x-axis points is 5; 9-4=5
2.
a. (3, 1) and (3, 5) because if you remove the -, it will be (3, 1) and (3, 5).
b. (-2, -6) , (-2, -10) , (2, 6) , and (2, 10).
b. All you have to do is get 2 points that are negative, and for the other 2 coordinates, remove the negative sign.
Hope this helped☺☺
