Main Concepts and Formule Chapter 3 Class 9 Mathematics Co-ordinate Geometry

- 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

- $\quad$ 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

- $\quad(x, y)$ 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 $(+,-)$
