Coordinate plane with voice
- 3. Formed by two real number lines that intersect at a right angle y y-axis (vertical line) 8 6 4 2 x-axis x -10 -5 5 10 (horizontal line) -2 -4 -6 -8 The center is called the origin!
- 4. 4 Quadrants Labeled Counterclockwise y 8 6 II 4 I 2 -10 -5 5 10 x -2 III -4 IV -6 -8
- 5. Plotting an Ordered Pair Plot the ordered pair (3,4) and label it. y 8 1. Start at the origin and 6 move 3 units to the right 4 A Label 2 2. Move 4 units up -10 -5 5 10 x 3. Place your -2 point. Try these! Click here! -4 -6 -8
- 6. An ordered pair is also know as coordinates. Written in the form (x,y) The x units is the distance along the x-axis and y is the distance along the y-axis.
- 7. Click to reveal Order Pair Practice answers 1. What are the coordinates y of Point B? 8 (-5, -4) 6 2. Plot the point C (-2, 0) 4 3. What are the coordinates 2 of Point D? C (6, -2) -10 -5 5 10 x -2 D -4 B -6 -8
- 8. Points are labeled using capital letters. The x and y axis intersect at their zero points. Therefore the coordinates of the origin is (0,0). Points that are not in the quadrants we say they lie on the x-axis or y-axis..
