1 Hand eye co-ordination can help your child to catch a ball and hit a ball with a bat.  Handwriting: Visual-motor integration, which is a vital skill for handwriting, grows out of a good hand-eye co-ordination base. The eyes need to guide the hand in forming the letters and making sure they stay within the lines.
The horizontal axis of a graph is also known as the x axis. Typically, the horizontal axis describes a quantity that changes in a predictable fashion. In the case of a scientific experiment, the horizontal axis usually denotes the control variable. This variable is deliberately controlled by the experimenter in order to determine the effects that change has on other variables.
We can also have the situation where the axis of the parabola is horizontal: In this case, we have the relation: (not function) y 2 = 4px [In a relation, there are two or more values of y for each value of x. On the other hand, a function only has one value of y for each value of x.] The above graph's axis of symmetry is the x-axis. Example - Parabola with Horizontal Axis . Sketch the curve and find the equation of the parabola with focus (-2,0) and directrix x = 2. Show answer. Shifting the Vertex of a Parabola from the Origin
