Explanation:

To solve this matching problem, we analyze each definition and match it to the correct scientific term:

1. "The factor that is changed or manipulated during an investigation."

This defines the independent variable (the variable the experimenter controls to observe its effect on another variable).

2. "The factor in an investigation that depends on the independent variable."

This defines the dependent variable (the variable that responds to changes in the independent variable).

3. "A line used to describe data and predict where new data will appear on the graph."

This defines a trend line (or "line of best fit"), which models data patterns and enables prediction.

4. "A relationship in which the..." (Assuming this refers to a relationship between variables, e.g., "A relationship in which the dependent variable changes with the independent variable" – this would describe a correlation or the general relationship between variables, but the key here is matching the given definitions to standard terms. However, based on the first three, we focus on the provided definitions:

Final Matches:

• "The factor that is changed or manipulated during an investigation." → Independent Variable
• "The factor in an investigation that depends on the independent variable." → Dependent Variable
• "A line used to describe data and predict where new data will appear on the graph." → Trend Line (or Line of Best Fit)

(Note: If the fourth definition is "A relationship in which the [variables are related]" (e.g., direct/indirect relationship), it would correspond to a "correlation" or "functional relationship," but the primary matches for the given three definitions are as above.)
