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

Points $A(5,3)$,$B(-2,3)$,and $D(5,-4)$ are three vertices of a square $ABCD$. Plot these points on a graph paper and hence find the coordinates of the vertex $C$.

The point for which the $x$-coordinate is positive and the $y$-coordinate is negative lies in the $\ldots \ldots \ldots$ quadrant.

Which of the following points lie on the $y$-axis?
$A(1,1), B(1,0), C(0,1), D(0,0), E(0,-1)$
$F(-1,0), G(0,5), H(-7,0), I(3,3)$

The points (other than origin) for which abscissa is equal to the ordinate will lie in

The perpendicular distance of the point $P(3, 4)$ from the $y$-axis is
