POINT A AND POINT B ARE 5 UNITS APART .THE COORDINATES OF POINT A ARE (3,-9).THE y COORDINATES OF POINT B IS -9 .WHAT IS A POSSIBLE X-COORDINATE FOR POINT B?

Answer 1

8, -2.
The y coordinate doesn't change, so you just have to add & subtract 5 from 3 in order to get all possible x coordinates without moving from -9.
