Graphing on a coordinate plane

Watch this step-by-step tutorial on how to read
ordered pairs.

• Study Jams- Ordered Pairs

• A coordinate plane is formed by two perpendicular
  lines called axes, that lie in the plane.

A coordinate plane is formed by two
perpendicular lines called axes, that lie in a
plane.
4
The Vertical Axis Is the Y-axis
The horizontal axis is the x-axis
5
Y- axis
X - axis
An ordered pair is.
6
Y- axis
X - axis
To find the ordered pair for a point, we go
across the x-axis and up the y- axis. For Point
D we go over 3 spaces and up 1 space
the ordered pair would be (3, 1)

(x, y)
7

• When plotting a point, just think of the
  alphabet.
• X comes before Y,
• which is true about the ordered pairs.
• (x, y)
• (across, up)

8
What point can be found at (1,3) ?
Point A is correct!!!
