Toggle## Class 9, Maths, Chapter 3, Exercise 3.2, Solutions

**Q.1. Write the answer of each of the following questions:**

**(i) What is the name of horizontal and the vertical lines drawn to determine the**

**position of any point in the Cartesian plane?**

**(ii) What is the name of each part of the plane formed by these two lines?**

**(iii) Write the name of the point where these two lines intersect.**

**Ans:**

(i) The name of **horizontal line** is **x – axis** and name of **vertical axis** is **y-axis**.

(ii) The name of each part of the plane divided by axes is ** quadrant**.

(iii) The axes intersect at **the origin**.

**Q.2. See 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.**

** **

**Ans:** Clearly, from the figure:

(i) The coordinates of B are (- 5, 2).

(ii) The coordinates of C are (5, – 5).

(iii) The coordinates (- 3, – 5) are identified by the point E.

(iv) The coordinates (2, – 4) are identified by the point G.

(v) The abscissa of the point D is 6.

(vi) The ordinate of the point H is – 3.

(vii) The coordinates of the point L are (0, 5)

(viii) The coordinates of the point M are (- 3, 0).
