The abscissa of a point is positive in:

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

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

The points $(1, -1), (2, -2), (4, -5), (-3, -4)$:

Which coordinate of a point on the $y$-axis is zero?

The coordinates of the origin are $\ldots \ldots \ldots$
