Question

the graph below shows the numbers of wins by a basketball team over six years.
(a) what was the greatest number of wins in a year?
wins
(b) when did the greatest increase in wins occur?
2020 to 2021
2021 to 2022
2022 to 2023
2023 to 2024
2024 to 2025

Explanation:

Step1: Identify peak win value

Locate the highest data point on the line graph, which corresponds to 2021. The value is 34 wins.

Step2: Calculate year-over-year win changes

• 2020 to 2021: $34 - 26 = 8$
• 2021 to 2022: $28 - 34 = -6$ (decrease)
• 2022 to 2023: $30 - 28 = 2$
• 2023 to 2024: $23 - 30 = -7$ (decrease)
• 2024 to 2025: $18 - 23 = -5$ (decrease)

Step3: Find largest positive increase

Compare the positive values: 8 and 2. The largest is 8, from 2020 to 2021.

Answer:

(a) 34
(b) 2020 to 2021
