The horizontal number line is the X Axis and the vertical number is the Y Axis.
This creates 4 quadrants. (Q I, Q II, Q III, Q IV)
 It also allows for any point in a quadrant to be located by calling out the X axis number followed by the Y axis number.
See the example below.
For Grade 5 - Students only need to identify locations in the first quadrant.
