1 The Coordinate Plane By: Christine Berg Edited By:VTHamilton

2 Definition The plane formed when 2 perpendicular number lines intersect at their zero points Coordinate Plane Coordinate Plane

3 Coordinate Plane The perpendicular number lines form a grid on the plane

4

5 X-axis The horizontal number line Positive to the right Positive to the right Negative to the left Negative to the left

6 Y-axis The vertical number line Positive Positive upward Negative Negative downward

7 Origin Where the x and y axes intersect at their zero points

8

9 Quadrants The x and y axes divide the coordinate plane into 4 parts called quadrants

10 I II III IV

11 Ordered Pair A pair of numbers (x, y) assigned to a point on the coordinate plane

12 Ordered Pair (x, y) X-coordinate Y-coordinate

13 Plotting a Point Step 1: Begin at the Origin

14 Plotting a Point Step 2: Locate x on the x-axis

15 Plotting a Point Step 3: Move up or down to the value of y

16 Plotting a Point Step 4: Draw a dot and label the point

17 In Your Own Words What What is a coordinate plane? Define Define origin How How do you plot a point?
