This question appears as Exercise 9.2, Question 1 in the NCERT textbook. The solution follows from the concept that the x-axis consists of all points whose y-coordinate is zero, hence y = 0. Similarly, the y-axis consists of all points whose x-coordinate is zero, hence x = 0. This logic is consistent with Example 4 in the context, which shows that a line parallel to the x-axis has equation y = constant, and a line parallel to the y-axis has equation x = constant. For the axes themselves, these constants are zero.
