To analyze the equation \( 8x - 3y = 2x + 9y \) and the statements provided, let's define key terms:

- **Variables**: Typically, the symbols representing unknowns, in this case \( x \) and \( y \).
- **Constants**: Fixed numerical values that do not change.
- **Coefficients**: The numerical factor in front of variables.

Now let's evaluate the statements:

1. **There are four variables.**
- This statement is **incorrect**. There are only two variables: \( x \) and \( y \).

2. **8 is the only factor of 8x.**
- This statement is **misleading**. While 8 is a factor of \( 8x \), \( x \) itself is also a factor since \( 8x = 8 \cdot x \). Therefore, it's not accurate to say 8 is the only factor.

3. **8, −3, 2, and 9 are constants.**
- This statement is **incorrect**. The numbers \( 8, -3, 2, \) and \( 9 \) are coefficients of the variables \( x \) and \( y \), not constants.

4. **8, −3, 2, and 9 are coefficients.**
- This statement is **correct**. In the equation, \( 8 \) is the coefficient of \( x \), \( -3 \) is the coefficient of \( y \) on the left side, and \( 2 \) and \( 9 \) are coefficients of \( x \) and \( y \) respectively on the right side.

The correct statement is:
**8, −3, 2, and 9 are coefficients.**
