The point of intersection of the $x$-axis and the $y$-axis is called $\ldots .$

Point $(2.8, 4.9)$ lies in the $\ldots \ldots$ quadrant.

Write whether the following statements are True or False. Justify your answer.
$(i)$ The coordinates of a point whose ordinate is $-\frac{1}{2}$ and abscissa is $1$ are $(-\frac{1}{2}, 1)$.
$(ii)$ $A$ point lies on the $y$-axis at a distance of $2$ units from the $x$-axis. Its coordinates are $(2, 0)$.

Without plotting the points,indicate the quadrant in which they will lie,if:
$(i)$ abscissa is $-5$ and ordinate is $3$
$(ii)$ ordinate is $5$ and abscissa is $3$

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 $C$.

In the figure,$LM$ is a line parallel to the $y$-axis at a distance of $3$ units.
$(i)$ What are the coordinates of the points $P, R,$ and $Q$?
$(ii)$ What is the difference between the abscissa of the points $L$ and $M$?
