7 The table shows some values for y= 1+2/x,given correct to 2 decimal places where appropriate. (a) Complete the table. (b) Draw the graph of y= 1+2/x for 0.5=<x=<8. (c) The line L crosses the graph of y= 1+2/x at x=2 and x=5. Find the equation of L. (d) A line with gradient -1/3 crosses the graph of y=1+2/x when x = 1 and when x = k. By drawing a suitable line on your grid, find k.
