Analytical geometry deals with algebraic representation of geometrical figures. It pertains to representation of geometrical figures on a coordinate system.
However, we've probably been doing so on charts that look like this: But since we're blasting ahead in math, we'll soon be graphing on charts that look like this: This is called a Cartesian coordinate graph. It's made up of two axes (axes is just the plural of axis): The horizontal axis is called the x-axis. And the vertical one is the y-axis. When the two axes meet, they form four quadrants.
