lies Locate and graph ordered pairs on the
coordinate plane

Vocabulary

• Coordinate plane Formed by two number lines in a
  plane that intersect at right angles.
• Axes Two number lines in a coordinate plane.
  X-axis is horizontal and y-axis is vertical.
• Quadrants The four sections created by the
  intersection of the axes.
• Ordered pairs Gives the location of a point on a
  coordinate plane.
• Coordinate The numbers in an ordered pair.

A coordinate plane is formed by two number lines
in a plane that intersect at right angles. The
point of intersection is the zero on each number
line.

• The horizontal axis is called the x-axis.

• The vertical axis is called the y-axis.

• The point where the axes intersect is called the
  origin.

Questions Notes
The first number tells how far to move right
(positive) or left (negative) from the origin.
The second number tells how far to move up
(positive) or down (negative).
What does an ordered pair tell you?
What is the ordered pair of the origin?
(0,0)
Quadrant I (, ) Quadrant II (-, ) Quadrant
III (-, -) Quadrant IV (, -)
What are the characteristics of the quadrants?
