Q1. Answer the following questions:
(i) Name the horizontal and the vertical lines drawn to determine the position of any point in the Cartesian plane?
(ii) Name each part of the plane formed by the above two lines?
(iii) Name the point where these two lines intersect.
(i) The name of horizontal and vertical lines drawn to determine the position of any point in the Cartesian plane is x-axis and y-axis respectively.
(ii) The name of each part of the plane formed by these two lines x-axis and y-axis is quadrants.
(iii) The point where these two lines intersect is called origin.
Q2. Answer the following referring to the figure given below:
(I) co-ordinates of B.
(II) co-ordinates of C.
(III) co-ordinates of the point L.
(IV) co-ordinates of the point M.
(V) ordinate of the point H.
(VI) abscissa of the point D.
(VII) The point i.e. identified by the co-ordinates
(VIII) The point i.e identified by the co-ordinates
(i) The co-ordinates of B is
(ii) The co-ordinates of C is
(iii) The co-ordinates of the point L is
(iv) The co-ordinates of the point M is
(v) Ordinate means y coordinate of point H. So, ordinate of point H is -3.
(vi) Abscissa means x co-ordinate of point D. So, abscissa of the point D is 6.
(vii) The point identified by the coordinates
(viii) The point identified by the coordinates
