We know that, the co-ordinates of a point on the y-axis are of the form (0, y). The point (0, y) lies on the negative direction of the y-axis if y is negative.
The point lies on the y-axis so its x-coordinate is 0. Also, the point is at a distance of 5 units in the negative direction of y-axis so its y-coordinate is −5. Thus, the point is (0, −5).
The point which lies on y-axis at a distance of 5 units in the negative direction of y-axis has the coordinates __(0, −5)__.
