## Chapter 6 Coordinate Geometry Ex 6.2

**Question 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.** **Solution:** **(i)** Horizontal line is known as X-axis and vertical line is known as y – axis. **(ii)** Each part of the plane formed by horizontal and vertical lines is known as quadrant. **(iii)** Horizontal and vertical lines intersect at the origin.

**Question 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 I.** **(viii) The coordinates of the point M.** **Solution:** **(i)** The coordinates of B = (-5, 2) and 6 lies in ∥ quadrant.

(∵ Abscissa = – 5, Ordinate = 2) **(ii)** The coordinates of C = (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 = 6 **(vi)** The ordinate of the point H = – 3 **(vii)** The coordinates of the point L = (0,5) (Lies on Y-axis) **(viii)** The coordinates of the point M = (-3,0) (Lies on X-axis)
