State whether the following statement is true or false:
$(0, 7)$ is a point on the $y$-axis.

Any point on the $y$-axis is of the form

The point $(0, -7)$ lies:

What is the measure of the angle formed by the coordinate axes (in $^{\circ}$)?

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 $(a, b)$ and $(b, a)$ represent the same point in the coordinate plane,then which of the following is possible?
