Rational Numbers on the Coordinate Plane

What is the coordinate plane

A surface made by two number lines crossing

What is the x axis

The horizontal number line

What is the y axis

The vertical number line

What are coordinates

Written as x value y value

How are locations measured

On both axes by distance from zero the origin

What is the first step to plot a coordinate

Move along the x axis left or right

What is the second step to plot a coordinate

Move along the y axis up or down

How are coordinates always written

As x y

Example what place is at 1 2.5

Move 1 right and 2.5 up answer the store

Example what are the coordinates of the restaurant

Move left 4 and up 1 coordinates are -4 1

What do coordinates always start from

Zero the origin

What comes first in coordinates

X comes before Y

Position property

Each point has one unique coordinate pair

Rational number property

Coordinates can be fractions or decimals

Order property

X is always listed first Y second
