Which of the following points lie on the y-axis?
       A (1, 1), B (1, 0), C (0, 1), D (0, 0), E (-1, 0), F (0, -1), G (4, 0), H (0, 7)

5 Solve the following equations:
(i) 3x + 3 = 15                    
(ii) 2y + 7 = 19
(iii) x + 3 =      
(iv) √3x – 2 = 2√3 + 4
(v) 8u + = 3u +7         
(vi) (√5 + 5)x + 4 = 2√5 + 8
(vii) 2x – (3x – 4) = 3x – 5    
(viii) 2x + √2 = 3x – 4 – 3√2 6 Which of the following points lie on the x-axis?
        (A) (3, 4)
       (B) (7, 0)
       (C) (0, 8)
       (D) (-9, 0)
       (E)
       (F) (-3, -5) 8 Draw the graph of equation x – 2y = 4. Read a few solutions from the graph and verify the same by actual substitution. In each case, find the points where the line meets the two axes. 9 Plot the points A (2, 0), B (2, 2), C (0, 2) and join OA, AB, BC and CO. What figure do you obtain ?
