Which coordinate of a point on the $y$-axis is zero?

Write the coordinates of the points marked on the axes in the figure.

The distance between the points $(5, -3)$ and $(5, 8)$ is............

Find the coordinates of the point:
$(i)$ which lies on both $x$ and $y$ axes.
$(ii)$ whose ordinate is $-4$ and which lies on the $y$-axis.
$(iii)$ whose abscissa is $5$ and which lies on the $x$-axis.

If $a=2, b=-3, c=-2$ and $d=-5,$ then the point $(ab, cd)$ is in the ......... quadrant.

If $a=5, b=7, c=6$ and $d=10,$ then the point $(a-b, c-d)$ lies in the ......... quadrant.
