## 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

first, then the number of

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

**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.

The grid then has four areas called quadrants.
