Plane A flat surface extending in all directions. A plane is a two-dimensional figure.

Coordinate Plane or Cartesian Plane (-5, 2) (4, 4) (-3, -3) (3, -6) The plane formed by a horizontal axis and a vertical axis, often labeled the x-axis and y-axis, respectively.

Coordinates or Ordered Pair On the coordinate plane, the pair of numbers giving the location of a point (ordered pair). Example: (1,2)

Coordinate or Point The coordinates are put together by the two axis. (X,Y)

Point of Origin or Origin On the coordinate plane, the point (0, 0). That is, the point of intersection of the x- and y-axes.

Origin Origin is where the X axis and Y axis intersect Origin (0,0)

X & Y Axis ( remember over, up or down) X-Axis-- The first coordinate is the horizontal position. (X,Y) Y-Axis-- The second coordinate is the vertical position. (X,Y)

X & Y Coordinates ( first number, last number) X-Coordinate-- The first number in the ordered pair. (*X,Y) Y-Coordinate-- The second number in the ordered pair. (X,*Y)

Quadrants 1) I (+,+) 2) II (-,+) 3) III (-, -) 4) IV (+,-) There are four Quadrants 1) I (+,+) 2) II (-,+) 3) III (-, -) 4) IV (+,-)
