Final answer:
Sam would be Standing at the coordinates (-18, 6) on the coordinate grid, indicating he is 18 yards behind the midfield stripe and 6 yards from the sideline. Option b
Step-by-step explanation:
In a soccer game, placing Sam on a coordinate grid based on the description would entail choosing a system where the midfield stripe is the x-axis and the sideline is the y-axis.
Given Sam kicked the ball from 18 yards behind the midfield stripe and 6 yards from the sideline, we can treat the midfield stripe as the origin (0,0) for the x-coordinate and the sideline as the origin for the y-coordinate.
Since Sam is behind the midfield stripe, he is in the negative x-direction, and since he is away from the sideline, he is in the positive y-direction. Therefore, his position on the coordinate grid would be (-18, 6), which corresponds to option b.
