The second problem of mathematics in the first day of junior high school
(10) Xiaoming drew a triangle in a plane rectangular coordinate system. If he translates the triangle to the right by five unit lengths, the abscissa of the three vertices of the triangle is _ _ _ _ X coordinate _+5 _ _ _ _ _ _ _ _, and the ordinate is _ original Y coordinate _ _ _ _ _ _ _ _ _ _ _ _ _ _.

(1 1), walk north from Xinhua Bookstore 100 meters to the shopping mall, and walk 250 meters west from the shopping mall to the gymnasium. If the coordinate of the gymnasium is (-250,0), the selected coordinate origin is _ _ _ _ _ _ _ _ _ _ _.

(13), in the plane rectangular coordinate system, the point A (-4,0) b (0,2) is known, and now the line segment AB is translated to make A coincide with the coordinate origin O, so the translated coordinate of point B is _ _ _ _ _ _ _ _ _ _ _ _.
