Answer: (3,1)

Step-by-step explanation:

Given:

The parabola, x2 = 9y

Let us assume the point be (3y1, y1).

Now by substituting the point in the parabola we get,

(3y1)^2 = 9(y1)

9y1^2 = 9y1

y1^2 – y1 = 0

y1(y1 – 1) = 0

y1 = 0 or y1 – 1 = 0

y1 = 0 or y1 = 1

The points is B (3(1), 1) => (3, 1)

∴The point is (3, 1).
