The distance of the point $(0, -6)$ from the origin is $\ldots \ldots \ldots$

If $a=5$ and $b=7$,then the point $(a-b, b-a)$ lies in the $\ldots \ldots \ldots$ quadrant.

The line joining $P (3, 2)$ and $Q (3, -5)$ intersects the $\ldots \ldots \ldots$ axis.

$A$ point lies on the $x$-axis at a distance of $7$ units from the $y$-axis. What are its coordinates? What will be the coordinates if it lies on the $y$-axis at a distance of $-7$ units from the $x$-axis?

Plot the following points and check whether they are collinear or not:
$(1,1), (2,-3), (-1,-2)$

The line joining $A(3, -8)$ and $B(3, 5)$ intersects the $x$-axis at $\ldots \ldots . .$
