To complete the table and write the equation for the relationship, we need more information about the pattern or the graph itself.

Here’s how we can determine the missing values and the equation:

1. Identify the Pattern or Relationship: If there is a consistent relationship between $x$ and $y$, such as a linear, quadratic, or other type of function, the equation can be deduced.
2. Equations for Common Patterns:
   • Linear: $y = mx + b$
   • Quadratic: $y = ax^2 + bx + c$
   • Others: Exponential, logarithmic, etc.

Please clarify or provide:

1. Is the graph linear or nonlinear?
2. Do you have additional points or a specific pattern?
3. Could you upload the graph or provide more context?

Alternatively, if you’d like, I can make reasonable assumptions based on patterns like a linear relationship.

Would you like me to proceed with that assumption?

Follow-Up Questions:

1. Could you provide the graph or a description of its shape?
2. Are there additional points that might clarify the relationship?
3. Is this a real-world scenario (e.g., physics, economics) that might suggest a specific type of function?
4. Are the $x$ values increasing by a consistent amount?
5. Would you like an example of a completed table based on common assumptions?

Tip: Graphing the points, even roughly, can help reveal patterns in the data.
