Slide 78 / 112 Coordinate Plane Click to return to the table of contents
Slide 79 / 112 Coordinate Plane The coordinate plane is formed by two intersecting number lines called axes. The horizontal line is the x-axis. The vertical line is the y-axis.
Slide 80 / 112 Coordinate Plane Origin (0, 0) The point at which the x and y axes intersect is called the origin. The coordinates of the origin are (0, 0).
Slide 81 / 112 Coordinate Plane y x Points can be plotted on the plane using one coordinate from each of the axes. These sets are called ordered pairs. The x coordinate always appears first in these pairs. The y coordinate appears second. (x,y)
Slide 82 / 112 Coordinate Plane To graph an ordered pair, such as(4,3): Start at the origin (0,0). Move right on the x-axis, since the first number is positive. Then, move up since the second number is positive. Plot the point. (4,3)
Slide 83 / 112 Coordinate Plane y x (x,y) This point is (3,2). To plot the point, go over 3, then up 2.
Slide 84 / 112 Coordinate Plane y x (x,y) This point is (1,4). To plot the point, go over 1, then up 4.
Slide 85 / 112 Coordinate Plane y x (x,y) This point is (5,0). To plot the point, go over 5, then up 0.

Slide 112 / 112 Coordinate Grid Geoboards Activity Work in partners. One partner creates a polygon on the geoboard and writes down the vertices. Other partner plots the points, and connects them with line segments. Compare the polygons, then switch roles.
