1. Coordinate Planes
2.2 I can identify the paths between points on a grid or coordinate plane and compare the lengths of the paths.
3.6 I can understand the coordinate system with positive X and Y values.

2. Coordinate Plane
Coordinate Plane - The plane where the ordered pairs (X,Y) are placed. The plane has a _________ (Side to Side) axis and a ________ axis (Up and Down).

3. Vocabulary Growing Pattern - A pattern that continues to go _____.
Ordered Pair ( X , ____ )
X tells you to start at 0 and go right or ______.
Then Y tells you to either go up or ______.

4. The point marked 0 is called the __________.Y X
(X,Y)
(4,3)
(2,0)

5. Coordinate Planes
Discuss in your group how an elevator would be similar to an ordered pair on a coordinate plane.
List Ideas:
Discuss how an escalator would be similar to an ordered pair on a coordinate plane.

6. How many units is A from B.
Coordinate Plane

7. Linear Equation - has a graph that is a straight line.
Examples: y = 3x
y = x + 2
To graph a linear equation, make a table to find several ordered pairs, graph the ordered pairs and then draw a straight line through the points.
Y = 2x X Y 1 2 3
