The Coordinate Plane

The x-axis and y-axis separate the coordinate plane into four regions,

called quadrants.

Direction of Movement for the X-Coordinate

If the x-coordinate is positive move this way

If the x-coordinate is negative move this way

Y-axis

X-axis

Direction of movement for the Y-coordinate

If the y-coordinate is positive move this way

If the y-coordinate is negative move this way

• Always start at the origin and move on the x-axis first when plotting n ordered

pair.
