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.

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).

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 ______.

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

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.

How many units is A from B. Coordinate Plane

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 Graph
