Multi-Step

Sean is growing a plant in a jar. He makes a graph to show the days since he put the seed in the jar, and the length of the longest root (in centimeters). He first sees the root in 4 days, and he writes the ordered pair (4, 2). Three days later, the root measures 18 cm. Five days later, it has grown another 25 cm. What ordered pairs does Sean add to his graph?

• (7, 18), (12, 43)

• (18, 3), (25, 5)

• (3, 18), (5, 25)

• (18, 7), (43, 12)

Marie was in fifth grade when she began to record her baby sister’s height and her own height in inches every six months for 3 years.

Do you think the weight of the bird feeder will be 10 ounces on day 6?

• The data shows that the weight increases over the 5 days. So, the weight on day 6 will be more than 10 ounces.

• The data shows that the weight decreases over the 5 days. So, the weight on day 6 will be less than 3 ounces unless the bird feeder is refi lled.

• (20, 35)

• (10, 20)

• (85, 40)

• (90, 50)
