What are the coordinates for each equation.
equations don't have coordinates. They represent lines, which meet at a point, whose coordinates in this case are (-2,6)
You might as well start now to express mathematical ideas in correct terminology. Otherwise, when you ask for help, people may not know what it is you really want to know. That may not bother you, but the wrong answers you may receive will probably not be of much help.
