Terms • Ordered pairs • a list of two numbers that describes the location of a point on a coordinate plane. (0,2) • X-Coordinate • shows the position left and right (horizontal) of the coordinate plane. It is the first number in the ordered pair. • Y-Coordinate • shows the position up and down (vertical) of the coordinate plane. It is the second number in the ordered pair.
Graphing Skills • Set of ordered pairs (-3,2), (3,4), (0,0), (-5,-6) • Steps for graphing • 1st graph the x-coordinate • Right or left • 2nd graph the y-coordinate • Up or down • 3rd Graph the point with a dot • 4th label the points B (A) C D
