# Coordinate Plane

How to draw a point on a coordinate plane: definition, 4 examples, and their solutions.

## Definition

### x-axis, y-axis, Origin

A Coordinate plane has two axes.

The x-axis is the horizontal axis.

The y-axis is the vertical axis.

And the origin is the intersection of these two axes.

### Quadrants

By the x-axis and the y-axis,

the coordinate plane is divided into four quadrants.

Quadrant I (First Quadrant):

where x > 0, y > 0

Quadrant II (Second Quadrant):

where x < 0, y > 0

Quadrant III (Third Quadrant):

where x < 0, y < 0

Quadrant IV (Fourth Quadrant):

where x > 0, y < 0

## Example 1

### Example

### Solution

Start from the origin.

The x coordinate of (4, 3) is 4.

So move 4 units to the right.

The y coordinate of (4, 3) is 3.

So move 3 units upward.

Draw a point on the endpoint.

This point is (4, 3).

## Example 2

### Example

### Solution

Start from the origin.

The x coordinate of (-5, 1) is -5.

So move 5 units to the left.

The y coordinate of (-5, 1) is 1.

So move 1 unit upward.

Draw a point on the endpoint.

This point is (-5, 1).

## Example 3

### Example

### Solution

Start from the origin.

The x coordinate of (-2, 0) is -2.

So move 2 units to the left.

The y coordinate of (-2, 0) is 0.

So don't move the endpoint:

neither upward nor downward.

Draw a point on the endpoint.

This point is (-2, 0).

## Example 4

### Example

### Solution

Start from the origin.

The x coordinate of (3, -5) is 3.

So move 3 units to the right.

The y coordinate of (3, -5) is -5.

So move 5 units downward.

Draw a point on the endpoint.

This point is (3, -5).
