The point $\left(-\frac{7}{2}, \frac{5}{2}\right)$ lies in the $\ldots \ldots \ldots$ quadrant.

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

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

In a Cartesian plane,the graph of $x=0$ is $\ldots \ldots \ldots$

See the figure and complete the following statements:
$(i)$ The abscissa and the ordinate of the point $B$ are ......... and ......... respectively. Hence,the coordinates of $B$ are (.........,.........)
$(ii)$ The $x$-coordinate and the $y$-coordinate of the point $M$ are ......... and ......... respectively. Hence,the coordinates of $M$ are (.........,.........)
$(iii)$ The $x$-coordinate and the $y$-coordinate of the point $L$ are ......... and ......... respectively. Hence,the coordinates of $L$ are (.........,.........)
$(iv)$ The $x$-coordinate and the $y$-coordinate of the point $S$ are ......... and ......... respectively. Hence,the coordinates of $S$ are (.........,.........)

$A$ point both of whose coordinates are negative will lie in
