Q.1.(b) Write the coordinates of a point on y-axis, which is at a distance of 3 units below x-axis.
 

Dear Student,

 

Since the point lies on the y-axis, its x-coordinate must be 0. Also, the point lies 3 units below the x-axis, so its y-coordinate is -3. Thus, the coordinates of the required point are (0,-3).
