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.

Y- axis
X - axisTo 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)
When plotting a point, just think of the alphabet.
X comes before Y,
which is true about the ordered pairs….
(x, y) (across, up)
What point can be found at (1,3) ?

Practice with Coordinate Plane
• Let’s do some practice problems on-line
• Individual Practice/HW: WB 149 #1-12
Day 2 – Length of Line Segments
1- Watch video Distance Between Two Points
2- Continue ppt
3- In-class Probe on screen (code provided)
4- Continue working on study guide– due tomorrow
How long is the line segment from the heart to the triangle?
Check out these practice problems. Log-in to take a probe and use the
following code.
