The scenario that could represent the given expression is D. Victor walks 8 blocks away from his home. He turns around and walks 2 blocks toward his home. Victor is 10 blocks from his home.
In scenario D, the number line with an arrow going from -2 to 8 represents Victor's movements. Initially, he walks 8 blocks away from home, indicating a negative displacement. Then, he turns around and walks 2 blocks toward his home, representing a positive displacement.
The final position is 10 blocks from his starting point. This mirrors the expression's representation of a journey from -2 to 8. The other scenarios involve different situations and do not align with the specified number line and arrow movement.
Therefore, scenario D accurately illustrates the expression's meaning on the number line.
