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.
X-axis. When referring to the cartesian plane, the x-axis or horizontal axis refers to the horizontal width of a two or three-dimensional object. The illustration shows the x-axis as going left-to-right and intersecting both the y-axis and z-axis. A good example of what uses the x-axis is a computer mouse. As the mouse moves left or right the x-axis value increases and decreases, which allows the computer to know where the mouse cursor is on the screen. Below is a JavaScript script, which if enabled shows you the mouses x-axis and y-axis position as you move your mouse on your screen.
