Answer:
The value stored there has changed to something new
Step-by-step explanation:
Given that Hand-tracing is a term in computer science that describes a form of miniature execution of codes. This is carried out through instructions and defined steps. Hand-tracing is done to cancel out the former value and depict the new value below it when there is a change in a variable.
Hence, during the process of Hand tracing, drawing a line through the value stored in a variable demonstrates that the value stored there has changed to something new.
