“I think; therefore I am.”
The x-axis is the Horizontal Axis.
The y-axis is the Vertical Axis.
The Origin is the Center of the
Coordinate Plane. Its Ordered Pair is (0, 0).
Notice how a Coordinate Plane is
made up of 4 squares?
These sections of squares are called
Quadrants. They are numbered: I, II, III, IV
Quadrant I(+,+)
Quadrant II(-,+)
Quadrant III(-,-)
Quadrant IV(+,+)
Question: What Quadrant does (-5, 3) lie?
Answer: Quadrant II
Graphing Ordered Pairs
What are the coordinates of Point B?
