Answer
Identify the concentration of enzyme on the x-axis and the mass of product formed on the y-axis.
Using the data from the table:
For 5 au: plot a point at (5, 15)
For 10 au: plot a point at (10, 22)
For 15 au: plot a point at (15, 32)
For 20 au: plot a point at (20, 38)
For 25 au: plot a point at (25, 40)
For 30 au: plot a point at (30, 40)
For 35 au: plot a point at (35, 40)
For 40 au: plot a point at (40, 40)
Ensure all points are plotted correctly with a tolerance of +/- ½ small square.

Answer
Draw a line connecting the plotted points to illustrate the trend.
Ensure the line shows a steady increase that levels off at 30 au/40 g.
