Thinking process (i) Firstly, check whether any coordinate of the given point is zero or not. (a) If x-coordinate is zero and y-coordinate is non-zero, then the point lies on the y-axis. (b) If y-coordinate is zero and x-coordinate is non-zero, then the point lies on the x-axis. (c) If x-coordinate and y-coordinate are zero, the point lies on the origin ( or on both the axes.) (ii) If none of the coordinates is zero, then the point lies in any one of the four quadrants. A) On the x-axis B) In the second quadrant C) On the y-axis D) In the fourth quadrant
How many of the following statements are correct? 1. If a point lies on the y-axis its x & z-coordinates are zero. 2. If a point lies on the x-z plane, its y-coordinate is zero.
3. The x-axis and y-axis taken together to determine a plane known as x-y plane.
