Cartesian system

Coordinate axes

Origin

Quadrants

Abscissa

Ordinate

Coordinates of a point

Ordered pair

Plotting of points in the cartesian plane:

• In the Cartesian plane, the horizontal line is called the x-axis and the vertical line

is called the y-axis,

• The coordinate axes divide the plane into four parts called quadrants,

• The point of intersection of the axes is called the origin,

• Abscissa or the x-coordinate of a point is its distance from the y-axis and the

ordinate or the y-coordinate is its distance from the x-axis,

• (x, y) are called the coordinates of the point whose abscissa is x and the ordinate

is y,

• Coordinates of a point on the x-axis are of the form (x, 0) and that of the point

on the y-axis is of the form (0, y),

•The coordinates of the origin are (0, 0),

• Signs of the coordinates of a point in the first quadrant are (+, +), in the second

quadrant (–, +), in the third quadrant (–, –) and in the fourth quadrant (+, –).
