(i) In order to plot these points, the given steps are to be followed: Take a point O on a graph paper and draw horizontal and vertical lines OX and OY respectively. Then, let on x-axis and y axis 1 cm represents 1 unit. In order to plot point (1, 1), we start from the origin O and move 2 cm along OX and 1 cm along OY. The point we arrive at is (1, 1). To plot point (1, 2), we move 1 cm along OX and 2 cm along OY. The point we arrive at is (1, 2). To plot point (1, 3), we move 1 cm along OX and 3 cm along OY. The point we arrive at is (1, 3). To plot point (1, 4), we move 1 cm along OX and 4 cm along OY. The point we arrive at is (1, 4).
