#### Important Terms on Coordinate Geometry

- Let XOX’ and YOY’ are two mutually perpendicular lines. These lines are called co-ordinate axis. XOX’ is called x-axis and YOY’ is called y-axis.
- Point of intersection of x-axis and y-axis i.e. O is called the origin whose coordinates are (0,0).
- x-coordinate of a point is called abscissa & y-coordinate is called the ordinate.
- Four Quadrants: A plane is divided by the axis in four quadrants given as follows:

- In first quadrant, both x and y coordinates of a point are + ve. For example (2, 3) lies in first Quadrant.
- In second quadrant, x-coordinate is – ve and y-coordinates is + ve. For example (-2, 3) lies in Second Quadrant.
- In third quadrant, both x and y coordinates of a point are negative. For example (-2, -3) lies in Third Quadrant.
- In fourth quadrant, x-coordinate is + ve and y-coordinate is – ve. For example (2, -3) lies in Fourth Quadrant.
