               SUBTOPIC: Cartesian System and Plotting of points


               1.    In which quadrant, the point P (-5,3) lies?                                         1

               2.    What is the name of each part of the plane formed by two perpendicular              1
                     lines?


               3.    Write the distance of point R (2,5) from Y-axis.                                    1

               4.    What is the ordinate of all points on X-axis?                                       1

               5.    In which quadrant the point P (x, y) will lie such that x< 0    and    > 0 ?        1


               6.     Identify the points which lie on y-axis.                                           2
                          (a) (0, 8)         (b) (0, 0)            (c) (4, 7)        (d) (-7, 0)

               7.    If (x-5, y-3) = (7, -2) then, find x + y.                                           2

               8.    Plot the points (1, 1), (2, -3) and (-1, -2) and check whether they are             2

                     collinear or not.

               9.    In which quadrant will the point lie (i) the ordinate is -7, abscissa is -5 and     2
                     (ii)abscissa -9, ordinate 5.
               10.  In which quadrant or on which axis do the following points lie:                      2

                     (a) (-1, -1)
                     (b) (0, -3)

                     (c) (2, -5)
                     (d) (-4, 2)


               11.  Find the co-ordinates of the vertices of an equilateral triangle of side ‘2a’        3
                     as shown in figure.
