# Coordinate plane parts review

Review the parts of a coordinate plane, and try some practice problems.

## Axes

A coordinate plane has one horizontal axis, the and one vertical axis, the .

## Origin

The and intersect at the . The is located at ordered pair, .

## Quadrants

The coordinate plane is divided into four quadrants. Quadrant one (QI) is the top right fourth of the coordinate plane, where there are only positive coordinates. Quadrant two (QII) is the top left fourth of the coordinate plane. Quadrant three (QIII) is the bottom left fourth. Quadrant four (QIV) is the bottom right fourth.
