The Coordinate Plane: The Coordinate Plane Formed by two real number lines that intersect at a right angle x-axis (horizontal line) x y y-axis (vertical line) The center is called the origin!

PowerPoint Presentation: x y Plotting an Ordered Pair Plot the ordered pair (3,4 ) and label it. A Start at the origin and move 3 units to the right Move 4 units up Place your point. Label Try these! Click here!
PowerPoint Presentation: 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.
Order Pair Practice: x y Order Pair Practice B 1. What are the coordinates of Point B? (-5, -4) 2. Plot the point C (-2, 0) C 3. What are the coordinates of Point D? Click to reveal answers D (6, -2)
Did you notice?: Did you notice? 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. .
