RN Teaching Coordinate Graphing

What number would go in the blank below?

A coordinate graph is a vertical and horizontal number

line intersecting at zero, zero for both.

Remember:

A horizontal line has positive numbers to the

right and negative numbers to the left as below.

-4

-3

-2

-1

Coordinate graphing is handy when describing a location

on a plane. The x axis divides the plane into two equal

sections on the horizon. The y axis is a vertical division.

Where the x and y cross is the origin. The origin is (0,0)

as all numbering starts at the origin.

The point (0, 0) is also called the .

The x axis goes sideways like a xylophone. The y axis

goes up and down like a yo yo.

The graph is divided into four sections as below. Since

all numbers are positive for both x and y in the upper,

right section or quadrant it is called quadrant I. In

coordinate graphing we move sideways first so the

second quadrant would be the upper, left quadrant.

See the Roman Numeral labeling below.

III

In coordinate graphing we move sideways first so the

second quadrant would be the upper, left quadrant.

Label quadrant II, III, and IV.

Remember: Sideways

first and up or down

second.

Points always move sideways first. This

point moved three right and two up making

the point (3, )

(-4, )

(-2, )
