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.
Illustration of a Cartesian coordinate plane, showing the absolute values of the coordinates of the points (2, 3), (0, 0), (â3, 1), and (â1.5, â2.5). The first value in each of these signed ordered pairs is the abscissa of the corresponding point, and the second value is its ordinate.
