Coordinate Plane

The Basics• All points on the coordinate plane have an address that is in the format of (x,y)

•The x-coordinate represents the horizontal location of the point

•The y-coordinate represents the vertical location of the point

•The origin is the represented by the coordinates (0,0)

Quadrants•There are 4 quadrants on the coordinate plane.

Locating Points• To find the location of any point on the

coordinate plane:

1. Look at the x-coordinate

2. Starting at the origin, go left or right the number of lines the x-coordinate represents

3. From that point, count up or down the number of lines the y-coordinate represents

4. Label the point

Remember This• Let’s think of some ways to remember that we need to go

left/right before we go up/down

• Let’s think of some ways to remember that a negative coordinate goes left/down and positive coordinate goes right/up
