Question

1. what quantities are being compared? (if there are x - and y - axes, what do they represent?) 3. what are 2 observations that you can make based on the graph?

Explanation:

• For question 2: The x - axis represents age (in years), and the y - axis represents two different percentages (possibly of two different groups or categories).
• For question 3:
• Observation 1: As age increases from 8 to 18 years, both percentages (represented by the two lines) increase.
• Observation 2: At each age from 8 to 18, the percentage of one group (the darker - colored line) is higher than the other group (the lighter - colored line).

Answer:

1. The x - axis represents age (in years). The y - axis represents two different percentages (likely of two distinct entities).

3.

• As age increases from 8 to 18, both percentages rise.
• For each age from 8 to 18, one percentage (darker - line) is higher than the other (lighter - line).
