You've probably already noticed that in the coordinate plane, the x- and y-axes split up the plane into 4 different regions.
Each region is called a quadrant.
Interact with the applet below, then answer the questions that follow.
What property do all the points (x,y) in first quadrant have in common? Explain.
For any point in the first quadrant, the x-coordinate and the y-coordinate are both positive.
What property do all the points (x,y) in the second quadrant have in common? Explain.
For any point in the second quadrant, the x-coordinate is negative the y-coordinate is positive.
What property do all the points (x,y) in the third quadrant have in common? Explain.
For any point in the third quadrant, the x-coordinate and the y-coordinate are both negative.
What property do all the points (x,y) in the fourth quadrant have in common? Explain.
For any point in the fourth quadrant, the x-coordinate is positive the y-coordinate is negative.
