1 The eyes need to guide the hand in forming the letters and making sure they stay within the lines. 2  Reading: Eye tracking skills, which are vital for reading, can be developed through games and activities used for hand eye coordination.  Play and Life Skills:
The ordered pair (x, y) is used to denote a point in Cartesian Coordinate system. It is the second of the two terms by which a point is referred to, in a system of fixed Cartesian Coordinate axes. The first coordinate, i.e., x coordinate, is called the abscissa. Cartesian co-ordinate system specifies each point uniquely in a plane by a pair of numerical co-ordinates, which are the distances from the point to two fixed axes, measured in the same unit of length.
The distance of a point from y-axis measured along the x-axis is called abscissa or x coordinate of the point and the distance of a point from x-axis measured along the y-axis is called ordinate.
