1.   Draw a line passing through (4, 5) and (5, 4). Find the coordinates of the points is a straight line.

2.   Show that the linear graph obtained by joining the following points is a straight line.

        (6, –3), (6, 1), (6, 4) and (6, 6)

3.   Look at the graph of a rectangle in the figure. What are the coordinates of its vertices?

4.   Draw a graph of ΔPQR, the coordinates of whose vertices are P(9, 5), Q(7, 7) and C(9, 9).

5.   Draw a ‘deposit-interset’ graph for the following data:
