(2) b) On graph paper, draw the graph of y = 3x + 1 (2) c) Use your graph to find (i) the of y when x = –0.8 (2) (ii) the value of x when y = 8. 2. A is the point (0, 1) B is the point (10, 6) Find the coordinates of the midpoint of AB. (1) 3. The diagram shows 4 straight lines, labelled P, Q, R and S. The equations of the straight lines are A: y = 2x B: y = 3 - 2x C: y = 2x + 3 D: y = 3 each straight line, P, Q, R and S to its equation. (3) 10 Statistics 1. A DIY store bought 1750 boxes of nails. Barry took 25 of these boxes and counted the number of nails in each. The table shows his results.
