Slide 2:
: The horizontal axis on a coordinate plane. -1 0 1 2 3 -2 -3 x X-axis
Slide 3:
: The vertical axis on a coordinate plane. 3 2 1 -1 -2 -1 0 1 2 3 -2 -3 -3 y x Y-axis
Slide 4:
: The x- and y-axes divided the coordinate plane into four regions. Each region is called a quadrant. 3 2 1 -1 -2 -1 0 1 2 3 -2 -3 -3 x y I II III IV Quadrant
Slide 5:
3 2 1 -1 -2 -1 0 1 2 3 -2 -3 -3 x y B A C D E Can you tell which quadrant each point lies in?
A
B
C
D
E III I IV II On the y-axis
Slide 6:
3 2 1 -1 -2 -1 0 1 2 3 -2 -3 -3 x y Ordered Pair: A pair of numbers that can be used to locate a point on a coordinate plane (X, Y).
Coordinate: One of the numbers of an ordered pair that locate a point on a coordinate plane. For example:
A (2, 2)
B (-1, 3)
C (-2 -1)
D (3 -2)
E (2, 0) Origin: The point where the x-axis and the y-axis intersect on the coordinate plane; (0,0). A B C D E
