**Question 1: Write the answer **to** each of the following questions:**

**(i) What is the name of **the **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.**

**Solution:**

(i)Name of the horizontal and vertical lines are:

- The horizontal line drawn on the Cartesian plane is known as x-axis.
- The vertical line drawn on the Cartesian plane is known as y-axis.

(ii)The name of each part of the plane formed by the two lines x-axis and y-axis is called as a quadrant (1/4^{th}part).

(iii)Name of the point where there two lines intersect is called the origin(O).

**Question 2: See the given 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.**

**Solution:**

(i)The coordinates of point B is the distance of point B from x-axis and y-axis that is −5 and 2 respectively.

Therefore, the coordinates of point B are (−5, 2).

(ii)The coordinates of point C is the distance of point C from x-axis and y-axis that is 5 and −5 respectively.

Therefore, the coordinates of point C 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 coordinates of point L is the distance of point L from x-axis and y-axis that is 0 and 5 respectively.

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

(viii)The coordinates of point M is the distance of point M from x-axis and y-axis that is −3 and 0 respectively. Therefore, the coordinates of point M is (−3, 0).
