Where's my point?
Drag the point A to different locations and note the 'quadrant' it ends up in.
How many quadrants can you identify?
Drag the point A to the intersection of the horizontal and vertical lines. Note what you observe.
Can you define the term 'Origin" now in a given Cartesian plane?
Do you see any pattern of the two numbers (within the bracket) about the point A in different quadrants?
Do you see how the location of point A is related to the pair of numbers in this given x-y plane?
Discuss the use of an "ordered pair" in a Cartesian plane (also called an x-y coordinate plane) in telling the position of a point. Illustrate why the order of the two numbers is important?
