Question

38. The number of bottles a machine fills is proportional to the number of minutes the

machine operates. The machine fills 250 bottles every 20 minutes. Create a graph that
shows the number of bottles, y, the machine fills in x minutes.

Answer 1

250/20 = 12.5/min

2 min = 25 bottles

The machine fills 25 bottles every two minutes. So you should make points (minutes, bottles) at (0,0), (2,25), (4,50), (6,75), (8,100), (10,125) and draw a line connecting them.
