Question

if a point is on negative side of y axis at a distance of 7 units from the origin find its co-ordinate

Answer 1

Since the point is on -ve side, the coordinate will become (x,-y).

since y is 7, The coordinate is (0,-7)

Answer 2

On y axis at a distance 7 is negative
so y is -7 and x is 0
The Co ordinate point is (x,y) = (0,-7)
