Based on the height record line graph for Collin, I can now answer each question:
1.
How tall was Collin when she was 4 years old?
Looking at the graph, at age 4 years (on the x-axis), the corresponding point on the line graph aligns with approximately 40 inches on the y-axis. So, Collin was about 40 inches tall when she was 4 years old.
2.
How much had Collin grown from the time she was born to 6 years old?
At birth, Collin's height appears to be around 20 inches. At 6 years old, her height is approximately 50 inches. The growth would be 50 - 20 = 30 inches.
3.
How old was Collin when she was 30 inches tall?
Looking at the graph, when Collin's height was 30 inches (on the y-axis), this corresponds to approximately 2 years old on the x-axis.
4.
How tall might Collin be when she is 10 years old?
The graph shows a consistent upward trend in Collin's height. From 8 years old (about 55 inches) to 10 years old, if we extrapolate the trend, she might grow another 5-10 inches. Looking at the options:
- a. 85 inches (too high, that would be over 7 feet)
- b. 55 inches (same as 8 years old, unlikely)
- c. 50 inches (less than at 8 years, impossible)
- d. 60 inches (reasonable increase of about 5 inches from 8 to 10 years)
The most reasonable answer is 60 inches.
5.
About how tall might Collin have been when she was 5 years old?
Looking at the graph, at 4 years old she was about 40 inches, and at 6 years old she was about 50 inches. At 5 years old, which is halfway between 4 and 6 years, she would likely be about halfway between 40 and 50 inches, so approximately 45 inches.
Looking at the options:
- a. 40 inches (same as 4 years old, unlikely)
- b. 43 inches (possible, but a bit low)
- c. 45 inches (most reasonable, halfway between 40 and 50)
- d. 49 inches (close to 6 years old height, too high)
The most reasonable answer is 45 inches.
Final Answers:
1. 40 inches
2. 30 inches
3. 2 years old
4. d. 60 inches
5. c. 45 inches
