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 $M$.
Solution
$(i)$ The $x$ – coordinate and the $y$ – coordinate of point $B$ are $-5$ and $2$ respectively. Therefore, the coordinates of point $B$ are $(-\,5,\,2)$.
$(ii)$ The $x$ – coordinate and the $y$ – coordinate of point $C$ are $5$ and $-5$ respectively. Therefore, the coordinates of point $B$ are $(5,\,-5)$.
$(iii)$ The point whose $x$ – coordinate and $y$ – coordinate are $-3$ and $-5$ respectively is point $E$.
$(iv)$ The point whose x-coordinate and $y$ – coordinate are $2$ and $-\,4$ respectively is point $G$.
$(v)$ The $x$ – coordinate of point $D$ is $6$. Therefore, the abscissa of point $D$ is $6$.
$(vi)$ The $y$ – coordinate of point $H$ is $-3$. Therefore, the ordinate of point $H$ is $-3$.
$(vii)$ The $x$ – coordinate and the $y$ – coordinate of point $L$ are $0$ and $5$ respectively. Therefore, the coordinates of point $L$ are $(0, \,5)$.
$(viii)$ The $x$ – coordinate and the $y $- coordinate of point $M$ are $-3$ and $0$ respectively. Therefore, the coordinates of point $M$ is $(-\,3,\, 0)$.
