A scientist is studying a certain species of caterpillar. She records the growth of a caterpillar from the time it hatches until it makes a cocoon, which usually takes about 2 weeks. During that time period, the caterpillar grows at a constant rate. It begins with a mass of 1.5 grams and grows at a rate of 0.2 grams per day. Which three of the following could she use in labeling the graph to represent her data?

• an x-axis showing time in days from 0 to 16

• an x-axis showing time in weeks from 0 to 2

• an x-axis showing time in months from 0 to 16

• a y-axis showing mass in grams from 0.5 to 4.0

• a y-axis showing mass in grams from 0 to 5
