The line joining $(8, 8)$ and $(-8, 8)$ is parallel to which axis?

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

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

If the coordinates of the two points are $P(-2, 3)$ and $Q(-3, 5),$ then (abscissa of $P$) $-$ (abscissa of $Q$) is

The line joining $(5, -3)$ and $(-5, -3)$ is $\ldots \ldots \ldots$

If the perpendicular distance of a point $P$ from the $x$-axis is $5$ units and the foot of the perpendicular lies on the negative direction of the $x$-axis,then the point $P$ has
