Question

A is a point on the y-axis at a distance of 4 units from the x-axis and lying below the x-axis. The coordinates of A are

(a) (4, 0)
(b) (0, 4)
(c) (−4, 0)
(d) (0, −4)

Answer 1

(d) (0, −4)
$$\begin{gathered} \text{It is}\mathrm{given}\text{that}\mathrm{point}A\mathrm{is}\mathrm{on}\mathrm{the}y-\mathrm{axis}\mathrm{at}\mathrm{a}\mathrm{distance}\mathrm{of}4\mathrm{units}\mathrm{from}\text{the}x-\mathrm{axis}\text{and lies}\mathrm{below}\text{the}x-\mathrm{axis}. \\ \text{Therefore},\mathrm{the}\mathrm{coordinates}\mathrm{of}A\mathrm{are}\left(0,-4\right). \end{gathered}$$
