(b) (i) Using a scale of 2 cm to 2 units on both axes, draw two perpendicular axes OX and OY on a graph sheet.
(ii) Mark the x-axis from –6 to 10 and y-axis from –6 to 14.
(iii) Using the table, plot all the points of the relation y=2x+5 on the graph.
(iv) Draw a straight line through the points.

(c) Use the graph to find
(i) y when x = 1.6
(ii) x when y = 10
