Question

a pair of polk high school hockey fans counted the number of games wor by the school each year. hockey games won by polk high according to the graph, when was the rate of change greater? between 2015 and 2017 between 2018 and 2019

Explanation:

Step1: Calculate rate 2015 - 2017

Time period: \(2017 - 2015 = 2\) years.
Games won change: \(18 - 6 = 12\) games.
Rate: \(\frac{12}{2} = 6\) games/year.

Step2: Calculate rate 2018 - 2019

Time period: \(2019 - 2018 = 1\) year.
Games won change: \(18 - 10 = 8\) games.
Rate: \(\frac{8}{1} = 8\) games/year.

Step3: Compare rates

\(8 > 6\), so 2018 - 2019 rate is greater.

Answer:

between 2018 and 2019
