See below figure, and write the following:

(i) The coordinates of $B$.
(ii) The coordinates of $C$.
(iii) The point identified by the coordinates $(-3

AcademicMathematicsNCERTClass 9

To do:

We have to find

(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:

From the graph, we can observe that,

(i) The X-coordinate of point $B$ is its distance from the Y-axis and the Y-coordinate of point $B$ is its distance from the X-axis.

Therefore, the coordinates of $B$ are $(-2, 5)$.

(ii) The X-coordinate of point $C$ is its distance from the Y-axis and the Y-coordinate of point $C$ is its distance from the X-axis.

Therefore, the coordinates of $C$ are $(5, -5)$.

(iii) The point identified by the coordinates $(-3, -5)$ is $E$.

(iv) The point identified by the coordinates $(2, -4)$ is $G$.

(v) The abscissa of the point $D$ is its distance from the Y-axis.

Therefore, the abscissa of point $D$ is $6$.

(vi) The ordinate of point $H$ is its distance from the X-axis.

Therefore, the abscissa of point $H$ is $-3$.

(vii) The X-coordinate of point $L$ is its distance from the Y-axis and the Y-coordinate of point $L$ is its distance from the X-axis.

Therefore, the coordinates of $L$ are $(0, 5)$.

(viii) The X-coordinate of point $M$ is its distance from the Y-axis and the Y-coordinate of point $M$ is its distance from the X-axis.

Therefore, the coordinates of $M$ are $(-3, 0)$.
