Grids
Introduction
Grids have 2 axes. The horizontal axis is called the x-axis and the vertical
axis is called the y-axis. These axis can be used to find a point on a grid.
These axes can be extended to include negative numbers as well as positive
numbers. This is called a grid with four quadrants.
Coordinates
A grid has an x-axis and a y-axis.
A point on a grid has two numbers to identify its position. These two numbers
are known as the point's coordinates.
Coordinates are always written as the number of steps across
first, then the number of steps up or down.
Point a) has coordinates of (2,4)
Point b) has coordinates of (4,2)

Grid with four quadrants
The x axis can be extended to the left into negative numbers and the y axis
can be extended down into negative numbers.
The grid then has four areas called quadrants.
The x axis can be extended to the left into negative numbers and the y axis
can be extended down into negative numbers.
