Answer 1

It seems like you're looking for clarification on why Lucy chose certain values or variables when creating an equation from a table in the Desmos calculator. However, because there are placeholders like " " in your question, I'm missing specific details to give a precise answer.

Here is a general explanation considering different scenarios:

1. **Standard Variables**: If Lucy used specific variables (like x and y) instead of others (like a and b), it is often because x and y are conventional variables for representing coordinates in a Cartesian plane, making it easier for others to understand her equations.

2. **Data Representation**: Lucy might have used certain specific values because those values corresponded to points in her table. For example, if her table represented values for a set of data points, she would want her variable choices to align with that data representation.

3. **Lucky Numbers**: While it's a more whimsical option, if "2" has significance to Lucy as a lucky number, she might choose it based on personal preference rather than mathematical necessity.

4. **Systems of Equations**: If Lucy was solving a system of equations, using two equations is standard. However, without knowing the context of her problem, it's hard to say if that was her reason.

Could you clarify the specific variables or equations Lucy was using? That way, I can provide a more targeted answer!
