A basketball coach collected data to analyze the free throw shooting percentages of players during a game and during practice. The equation y = 0.9x – 1 is a line of best fit for the data, where x is the practice shooting percentage and y is the game shooting percentage.
Based on the equation, what will be the approximate shooting percentage in a game for a player with a practice shooting percentage of 88?
O A. 78
B. 80
O c. 86
D. 99

The approximate shooting percentage in a game for a player with a practice shooting percentage of 88 is A. 78.

The equation is

y = 0.9x - 1

Where x = 88

y = 0.9 (88) - 1

y = 79.2 - 1

y = 78.2

The correct answer is option A; 78

Step-by-step explanation: The equation representing the line of best fit which is given as

y = 0.9x - 1

depicts the relationship between a player's practice results and actual game results. Whatever value is given as x which is the result from practice would be a good way of predicting a player's result when engaged in the real game.

For the question above, a player with  a practice shooting percentage of 88 would have his game shooting estimated by simply inserting the value of his practice percentage into the equation showing the line of best fit shown as follows;

y = 0.9x - 1

Where x = 88

y = 0.9 (88) - 1

y = 79.2 - 1

y = 78.2

y ≈ 78

Therefore the approximate shooting percentage for a player with a practice shooting percentage of 88 would be 78 percent.
