Which scatter plot represents the data shown in the table?
Which prediction equation represents the data shown in the table?
A. y = 2x + 94
B. y = 2x + 64
C. y = –2x + 94
D. y = –2x + 64
Use your prediction equation to predict the missing value.
A
The scatter plot shows the number of summer workouts the players on a basketball team attended and the number of wins during the following season. Predict the number of wins the team would have if they attended 24 summer workouts.
