If $a=5, b=3, c=-8$ and $d=-5$,then in which quadrant does the point $(a+c, b+d)$ lie?

The line joining $X(3, 5)$ and $Y(-4, 5)$ is parallel to the $\ldots \ldots \ldots$ axis.

How will you describe the position of a table lamp on your study table to another person?

See the figure and write the following:
$(i)$ The coordinates of $B$.
$(ii)$ The coordinates of $C$.
$(iii)$ The point identified by the coordinates $(-3, -5)$.
$(iv)$ The point identified by the coordinates $(2, -4)$.
$(v)$ The abscissa of the point $D$.
$(vi)$ The ordinate of the point $H$.
$(vii)$ The coordinates of the point $L$.
$(viii)$ The coordinates of the point $M$.

The point $(-10, 0)$ lies:

If the coordinates of the two points are $P(-2, 3)$ and $Q(-3, 5),$ then (abscissa of $P$) $-$ (abscissa of $Q$) is
