Cartesian Plane or Coordinate Grid

A Cartesian Plane is formed when a vertical (up and down) number line meets a horizontal (sideways) number line.

X-axis is the horizontal number line on a coordinate grid.

Y-axis is the vertical number line on a coordinate grid.

Origin is the point where the x-axis and the y-axis meet or intersect.

Quadrants are the four regions on the coordinate grid. They are labled using Roman numerals starting in the top right (I) working counter clockwise top left (II) bottom left (III) bottom right (IV)

Coordinates are the values in an ordered pair. The x value is always listed before the y value.

eg. (4,2)
