To represent \( 2 \cdot -15 \) with a model, we can interpret the expression as "2 times -15", which can be thought of as adding -15 two times. This can be represented as:

\[
-15 + -15
\]

This matches the response provided.

Thus, the correct response is:
\[
-(-15 + -15)
\] (or more simply, \(-15 + -15\))

This indicates the sum of two negative values, consistent with the multiplication of 2 and -15.
