1. Notes 7-2
The Coordinate Plane

2. Coordinate Plane:
Two number lines drawn perpendicular to one another, crossing at 0.

3. x – axis
the horizontal line on the coordinate plane
y - axis
the vertical line on the coordinate plane

4. Has the coordinate of (0, 0)
Origin -
The point on the coordinate plane where the lines cross
Has the coordinate of (0, 0)

5. Quadrants: Each section of the coordinate plane
The quadrants go in counter-clockwise order.

6. (x, y) Ordered Pair – Also known as a coordinate.
The x value tells how far to go sideways.
The y value tells how far to go up and down.

7. How to graph a point:
Step 1: find the x coordinate and move left or right on the x axis that many spaces (DO NOT COUNT ZERO)
Step 2: find the y coordinate and move up or down on the y axis that many spaces (DO NOT COUNT ZERO)

8. Graph the coordinates of each of the following points
Graph the coordinates of each of the following points. A(3, 2), B(-1, 3), C(-4, -1), D(6, -4)

9. Graph the coordinates of each of the following points
Graph the coordinates of each of the following points. E(-3, -6), F(1, -5), G(4, -4), H(0, -4)

10. Graph the coordinates of each of the following points
Graph the coordinates of each of the following points. I(0, -6), J(1, 0), K(4, 2), L(-3, 0)

11. Name two points that have the same x coordinate.
