If $(x+2, 7)$ and $(2x-1, 7)$ are the same point,then $x = $ ...........

The abscissa of all points on the $x$-axis is:

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

If $a=5, b=7, c=3$ and $d=-5,$ then the point $\left(\frac{a}{b}, \frac{c}{d}\right)$ is in the $\ldots \ldots$ quadrant.

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 (.........,.........)

Which quadrant does the interior of $\angle X^{\prime}OY^{\prime}$ represent?
