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 (+, –).
