Graphing on the Coordinate PlaneGraphing on the Coordinate PlaneObjective: To understand how to graph geometric shapes on the coordinate plane.

Graphing on the Coordinate PlaneAt the end of this lesson you should be able to answer the following question.

How can the coordinate plane be used to represent geometric figures?

Graphing on the Coordinate PlaneA coordinate plane is a grid with a vertical y-axis and horizontal x-axis.

y-axis

x-axis

Graphing on the Coordinate PlaneThe center of the coordinate plane is called the origin. y-axis

origin

x-axis

Graphing on the Coordinate PlaneThe coordinate plane is divided into four quadrants. Quadrant II y-axis Quadrant I

origin x-axis

Quadrant III Quadrant IV

Graphing on the Coordinate PlaneYou can use an ordered pair (x,y) to locate any point on the plane.

The first number in an ordered pair is the x-coordinate.

The second number in an ordered pair is the y-coordinate. Graphing on the Coordinate PlaneName the ordered pair and quadrant.
