Answer:
|x-10 y-4|
Step-by-step explanation:
Let the initial position where the football is thrown up the air be x and y.
After the ball is thrown up the air it moves 10 feet west 4 feet south because of the gust of wind.
Therefore the change in x is by 10 feet west and is at the point x - 10 and the change in y is by 4 feet south and is at the point y - 4.
Thus the matrix representing the position of the football is |x-10 y-4|.
