In which quadrant or on which axis do each of the points $(-\, 2,\, 4)$, $(3, \,-\, 1)$, $(-\, 1,\, 0)$, $(1,\, 2)$ and $(-\, 3, \,-\, 5)$ lie ? Verify your answer by locating them on the Cartesian plane.

See Fig., 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 $M$.

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

See Fig. 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 (……… , ………)

Plot the points $(x,\, y)$ given in the following table on the plane, choosing suitable units of distance on the axes.
