Question

Write the coordinates of a point lying on y-axis at a distance of 9 units in the negative direction.
(a) (0,-9)
(b) (0,9)
(c) (9,0)
(d) (-9,0)​

Answer 1

Answer:

Let the required point be P.

Given, the point lies on y-axis.

Then, its abscissa is 0 or x=0.

Also, given the point is at a distance of 2 units in the negative direction of y-axis,

So, its ordinate will be −2.

Hence, the co-ordinates of the required point are (0,−2).

Therefore, option C is correct.

Answer 2
