To evaluate the expression \(-2xy\) given \(x = -3\) and \(y = -1\), we can substitute the values into the expression:

\[
-2 \cdot (-3) \cdot (-1)
\]

Calculating step-by-step:

1. First, calculate \(-3 \cdot -1 = 3\).
2. Next, multiply by \(-2\):
   \[
   -2 \cdot 3 = -6
   \]

Thus, the value of \(-2xy\) is \(-6\).

It seems there may have been an error in the choices provided since \(-6\) is not listed. If you want to clarify or recheck the expression or values, please let me know.

Would you like further details or explanations? Here are some related questions you might consider:

1. What would the result be if \(x\) or \(y\) were positive?
2. How does changing the coefficients in the expression affect the result?
3. Can you provide a different expression to evaluate?
4. What are the rules for multiplying negative numbers?
5. How would you graph the equation based on the values of \(x\) and \(y\)?

**Tip:** Always double-check your calculations, especially with negative signs!
