Coordinate geometry

Coordinate geometry

1. COORDINATE AXES Two mutually perpendicular lines intersecting at the point called origin

   • QUADRANTS Each of the four parts of the plane divided by coordinate axes
   • X- AXIS Horizontal line
   • Y-AXIS Vertical line

2. COORDINATES

   • ABCISSA Distance of a point from y-axis
   • ORDINATE Distance of a poiny from x-axis
   • COORDINATES or ORDERED PAIR (x, y) is a point where x is abcissa and y is ordinate
   • Coordinates of the origin are (0, 0)
   • Coordinates of a point on x-axis are (x, 0)
   • Coordinates of a point on y-axis are (0, y)
