**We are all somewhat
familiar with the concepts of coordinate geometry if we have used a road map
to locate a place. In coordinate geometry, locations are made in terms of two
numbers or letters.**

**The simple grid below
is divided into four quadrants or sections with the central point being at (0,0).
The perpendicular axis are numbered from that central point to guide the user
as to the location of points in each quadrant t. The horizontal line in this
set of perpendicular lines is the X axis and the vertical line int his set of
perpendicular lines is the Y axis. **

**Click on the dots in
the grid below to find out what their locations are on the grid. **
