Question 1: In which quadrant or on which axis do each of the points (– 2, 4), (3, – 1), (– 1, 0), (1, 2) and (– 3, – 5) lie? Verify your answer by locating them on the Cartesian plane.
Question 2: Plot the points (x, y) given in the following table on the plane, choosing suitable units of distance on the axes.
Concept: This video tutorial is about what a Coordinate / Cartesian / XY Plane in Coordinate Geometry is. The concept has been explained with detailed examples. It is a recommended video for class 9 students.
Concept: This video tutorial explains that x-coordinate (abscissa) of a point in a cartesian plane is also its perpendicular distance from the y-axis. Similarly y-coordinate (ordinate) of a point is equal to the perpendicular distance of the point from x-axis.
Concept: In this video tutorial, you will learn about the basics of coordinate geometry. This is a must watch video tutorial for class 9 students. This video talks about the coordinate / cartesian plane in length with detailed examples. Different elements of coordinate plane like abscissa and ordinate are also explained with simple examples.
