What is the x-coordinate of a point on the y-axis? Class 9
Question 1.
What is the x-coordinate of a point on the y-axis? Class 9
Answer:
The x-coordinate of any point on the y-axis is 0.
Question 2.
Is there a similar generalisation for a point on the x-axis? Class 9
Answer:
Yes. For any point lying on the x-axis, the y-coordinate is always 0.
Question 3.
Does point Q (y, x) ever coincide with point P (x, y)? Justify your answer. Class 9
Answer:
Yes, points Q(y, x) and P(x, y) coincide only when x = y.
When x = y, both points represents the same point, for example P(3, 3) and Q(3, 3).
When x ≠ y, the two points represent different locations on the plane and do not coincide.
