**NCERT Solutions Class 9 Mathematics**

**Exercise 3.2**

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

- What is the name of horizontal and the vertical lines drawn to determine the position of any point in the Cartesian plane?
- What is the name of each part of the plane formed by these two lines?
- Write the name of the point where these two lines intersect.

**Q.2.** See Fig.3.14, and write the following:

- The coordinates of B.
- The coordinates of C.
- The point identified by the coordinates (-3, -5).
- The point identified by the coordinates (2, -4).
- The abscissa of the point D.
- The ordinate of the point H.
- The coordinates of the point L.
- The coordinates of the point M.

**Exercise 3.2**

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

- What is the name of horizontal and the vertical lines drawn to determine the position of any point in the Cartesian plane?
- What is the name of each part of the plane formed by these two lines?
- Write the name of the point where these two lines intersect.

**Solution:**

- The name of horizontal line is
**x-axis**and the name vertical line is**y-axis**. - The name of each part of the plane formed by these two lines x-axis and y-axis is
**quadrants**. - The point where these two lines intersect is called
**origin**.

**Q.2.** See Fig.3.14, and write the following:

- The coordinates of B.
- The coordinates of C.
- The point identified by the coordinates (-3, -5).
- The point identified by the coordinates (2, -4).
- The abscissa of the point D.
- The ordinate of the point H.
- The coordinates of the point L.
- The coordinates of the point M.

**Solution:**

- The coordinates of B are (-5, 2).
- The coordinates of C are (5, -5).
- The point identified by the coordinates (-3, -5) is E.
- The point identified by the coordinates (2, -4) is G.
- Abscissa means x coordinate. So, abscissa of the point D is 6.
- Ordinate means y coordinate. So, ordinate of point H is -3.
- The coordinates of the point L are (0, 5).
- The coordinates of the point M are (- 3, 0).
