The coordinate plane

Read ordered pairs and plot points while checking axes and order.

Meaning

A coordinate plane uses two perpendicular number lines to describe position. In the first number gives horizontal position and the second vertical position.

Example

is 2 units left and 3 up from the origin. It differs from Reversing coordinate order generally gives a different point. Read axis units and scale intervals too.

Practice for this concept

Scope and references

Topics

Ordered pairs, coordinate axes, origin, quadrants, point positions

Learning goal

Read ordered pairs and plot points while checking axes and order.

Helpful background

Apply number-line directions and units to each of two axes.

Plot a point on the coordinate plane

This practice does not assess all ordered-pair reading, graph drawing, or coordinate geometry skills.
